(CNN) -- Waleed Ahmed grins for the camera, a sly smile on his face as he poses in front of a black Porsche parked on the street.
At first glance, he looks like any other young guy hamming it up for an image to share with his buddies on Facebook.
Yet looks can be deceiving.
The Norwegian gained fame and fortune in his 20s -- enough to own that shiny, black Porsche in the photo -- after supposedly inventing an iPhone cover that uses solar energy to charge the phone.
Norway's media dubbed him the "Mark Zuckerberg of Norway," and the government even posted a video on its website of Ahmed and his then-business partner meeting with Norway's minister of trade and industry to show off the solar iPhone case.
Ahmed's fame led to numerous encounters with international royalty and well-known diginitaries, including the crown prince and princess of Norway, former United Nations Secretary-General Kofi Annan, former U.N. Ambassador Andrew Young and CNN founder Ted Turner.
Ahmed apparently wasn't just an innovative genius: He said he had been selected to be the chairman of Barack Obama's 2012 re-election campaign in Norway.
So, when Ahmed approached California investor Todd Weinberg last summer about his latest business proposition -- managing Justin Bieber's 2013 Scandinavian tour -- it didn't seem like a stretch that the young genius could secure the rights to the pop star's multimillion-dollar tour.
But the business deal between Ahmed and Weinberg would go terribly wrong. In the end, it would uncover a story that reads like the plot of a Hollywood movie.
The Bieber ruse
Last summer, Weinberg got a call from a friend in Los Angeles with connections in the entertainment industry about an amazing business opportunity.
"He said that he had come across an opportunity ... to help find money for an investor who could fill the gap for this tour that Justin Bieber is currently on," said Weinberg, a successful real estate investor and venture capitalist. "And I said, 'Well I don't understand, how does that work?' "
That so-called investor was Ahmed, 22, who claimed he had already paid $4.5 million to Scooter Braun Management -- Bieber's management company -- for rights to the Scandinavian tour after the initial investor failed to come up with the money.
But Ahmed said he needed another $1 million to secure the tour venues.
"Waleed wanted me to take the place of an investor who he had been working with that had fallen out of the deal," said Weinberg, 44.
Ahmed explained in an e-mail to Weinberg that he had gotten involved in the Bieber project because he "had the contacts to get a deal done with (Justin Bieber) because I am also working for President Obama as his election chair in Norway so easy to get things done."
For his $1 million, Weinberg said Ahmed assured him and his contract promised, that the return on his investment could be as high as $10 million.
Weinberg quickly went to work, trying to confirm the details.
"When we started looking and digging into the numbers, and (into) the spreadsheets and looking at actual ticket sales, per ticket sales, how many venues and how many tickets are being sold, it started to make sense," he said.
Even though it seemed like a sound investment, Weinberg admitted he was skeptical.
"When I was presented with my offer, my initial inclination was 'No thank you, not interested,' " Weinberg said. "It doesn't make sense to me, I have never done anything like this before. This is not my background. This is not my wheelhouse."
The contracts and other documents Ahmed provided to Weinberg all looked real. To make it appear legitimate, Ahmed even set up a conference call with a key member of Scooter Braun Management.
But Weinberg wanted to meet with Ahmed in person before moving forward with the deal.
Just four days after hearing about the Bieber opportunity, Weinberg headed to Burbank, California, where the young entrepreneur introduced Weinberg to the team he had assembled to promote Bieber's 2013 Scandinavian tour.
Even Miss Finland 2011, Pia Pikarinen, had been recruited to help promote the concerts.
Ahmed looked the part of a deal maker.
"He was Prada and Gucci from head to toe," Weinberg said. "He was a nice guy, but he also had a bit of an edge and arrogance about him."
It all looked like a good deal for everyone, and later that day, Weinberg and the rest of the team signed a contract at the offices of Karmic Management, one of three Los Angeles-based companies assigned to handle entertainment, public relations and sponsorships for the Bieber project.
But only Weinberg put up money.
Weinberg said he paid $860,000 to Ahmed to secure the concert venues and $140,000 to Karmic Management to get a website created and for other parts of the deal.
Ahmed sent Weinberg a text that the bank had confirmed the wire transfer of funds and said, "I just got a call from President Obama's election campaign since I am the chair for Norway so they need me in Chicago today, so heading over there now."
At that point, Weinberg said he thought the deal was on.
"After I invested the money, there was a lot of friendly collaborations happening," Weinberg said. "A lot of e-mails coming back and forth. Waleed was very involved and we started talking about who our ticketing agency was going to be, which was an organization that everyone has heard of. ... We hired a company to start developing a website for the Scandinavian leg of the tour."
But it wasn't long before, as Weinberg put it, "a couple of things went off track."
Conning the con man
First, Weinberg said he started getting nervous when Ahmed "went off the radar" for 10 days.
"Well, you can imagine after 10 days, we are freaking out," Weinberg said. "Something is not right. Well, he surfaces and tells us, 'I'm sorry, you know, I was basically out for a Muslim holiday. I was out for Ramadan, and I'm sorry, but I am back. Let's go.' "
Around the same time, Weinberg said he began to hear about problems with the company handling the ticket sales. Then, Ahmed appeared on a radio interview in Norway, talking about his latest clothing purchases.
"Shoes, jacket, I have more at home," Ahmed told NRK reporter Webjørn Espeland. "I was in the U.S. and shopped Louis Vuitton for approximately 60,000 NOK (Norwegian kroners)."
That's more than $10,000 in clothing.
The next week, Ahmed returned to the United States. Weinberg got on a plane and met him in New York for dinner.
"This whole thing was disturbing and extremely confusing. He was talking in circles, and nothing was adding up," Weinberg said.
Then, the ruse came to an abrupt end when Weinberg learned that tickets for Bieber's Scandinavian concerts went on sale and quickly sold out.
"We couldn't believe it," Weinberg said. "We never had the deal. So this is when all of the alarms started going off, of course. And that's when Waleed got really squirrelly and became very hard to reach."
Weinberg had had enough. He contacted the FBI.
Meanwhile, Ahmed was in Norway in late September. During that trip, he posed for photos to accompany the radio interview he had given to Norway's NRK.
He would then make a fateful decision to return one last time to the United States. Weinberg persuaded him to meet at a restaurant in San Francisco.
They sat in a booth near the front door. Weinberg wore a wire, recording the conversation for the FBI.
"For two hours, Waleed goes into this whole dissertation about how his life is over as he once knew it," Weinberg said. "The Waleed Ahmed of Norway, the Mark Zuckerberg, the celebrity, the guy that everybody was excited about has now become a disappointment."
Ahmed explained to Weinberg how his parents have disowned him, and how he is in such financial straits that he's going to lose his home -- even his new Porsche. He said he planned to start his life over in Pakistan, where he has an uncle in the real estate business.
"Meanwhile, he's dressed again, Prada and Gucci head to toe," Weinberg said. "He just flew in first class telling me that he's broke without realizing that he flew in style. I mean, this guy had again the audacity to just continue this lie with me, and I just wasn't buying it. But I was doing the best I could to bite my lip."
The next day, on September 23, 2012, the FBI arrested Ahmed at San Francisco International Airport before he boarded a flight to Amsterdam.
He admitted to the FBI that it was all a con job.
In addition, according to an FBI affidavit, Ahmed created fake websites and e-mail addresses to pull off the scam. The conference call with the supposed member of Scooter Braun Management was actually one of Ahmed's friends in Norway.
Other scams and close calls
Today, Ahmed no longer wears Prada and Louis Vuitton. He's behind bars at the Metropolitan Detention Center in Los Angeles. He pleaded guilty to conspiracy to commit wire fraud and is awaiting sentencing, scheduled for June 11. He refused a CNN request for an interview. The U.S. Attorney's Office and FBI also would not comment because Ahmed has not yet been sentenced.
But in a three-page letter to U.S. District Court Judge Philip Gutierrez, Ahmed wrote, "I have disgusted many, I have been the source of shame and disrespect for my friends, family, community and followers. I accept my crime, while I regret every bit of time, all I have with broken words, is that I really regret every minute spent committing it."
He told the judge that he "could not distinguish between right and wrong in the fire of desire and need for more."
As for the famous people he claimed to know, a spokesman for Scooter Braun said he never heard of Ahmed.
Ted Turner's spokesman said, "While Mr. Turner might have attended a public event in Norway where Mr. Ahmed was in attendance, he does not know Mr. Ahmed personally, and did not meet him in Atlanta."
Andrew Young said he did meet Ahmed and was shocked to learn he had been arrested.
"He used my contacts for things that I didn't know about nor did he ever discuss with me," Young said. "I mean, the first I heard from this was when he was arrested, and his lawyer called me and told me what he's been charged with, and my first reaction was there must be some misunderstanding."
The other companies that Ahmed lined up for the Bieber deal also said they were fooled.
Pikarinen, the Finnish beauty queen, said she knew nothing about any details of the deal.
"My company was scammed as well," said Carmenita Cornish-Helligar, the CEO of Karmic Management, who hosted the contract signing after learning about Ahmed through an entertainment industry contact in London.
"I still have fallouts from it," she said.
After Ahmed's arrest, other details of what led to the Bieber scam started to emerge.
Months before Weinberg was approached, Ahmed was trying to line up other investors, including Atlanta businessman Robert Fowler.
"I almost got suckered into the same thing," said Fowler, who said he turned down the deal after he found out it wasn't legitimate.
As it turns out, the Bieber con wasn't the only trouble for Ahmed.
In 2011, he made a deal with an Atlanta medical supply company to distribute specialty medical gloves called "EKG gloves" to the Middle East. But the deal went sour, and the company was stuck with thousands of the gloves.
"He's a really good con artist," said the company's owner, Billy Williams.
His company, Affirmative Solutions, sued Ahmed and obtained a court judgment against him for money owed in the deal.
Not only that, court documents from Norway reviewed by CNN show that Ahmed received a suspended jail sentence and was fined in 2008 for forging paperwork when he was 17, to get into a school.
In 2011, he was investigated for insurance fraud for claiming his BMW had been stolen in Oslo.
Five months before Ahmed met Weinberg, he bilked another investor out of $600,000 in another investment scam after pretending he was part of a development project, according to the Norwegian court documents.
Even the supposed iPhone solar charger that made him famous in Norway may not be his own invention, according to Norwegian press reports, which also revealed that Ahmed had made up how many devices had been ordered.
In a 37-page document filed with the court on June 3, the government argues for a 100-month prison term, citing Ahmed's history of criminal activity. His attorney is asking for an 18-month sentence.
"In reviewing defendant's communications, I was struck by how much pleasure he got out of betraying victim's trust, and his lack of respect for the victim," wrote FBI Special Agent Alice Tsujihara.
"Defendant texted that he should get the 'Best Scandinavian Thieves' award' and that 'being a thief is a profession.' "
A friend in Norway who went to business school with Ahmed helped him pull off the Bieber scam, she wrote, by creating false documents and posing as business associates.
"To defendant, fraud was 'like poker or blackjack' where you 'call or raise. Never fold!' " Tsujihara wrote.
Weinberg said he didn't know anything about Ahmed's previous troubles. As of now, he hasn't gotten any of his money back.
"I feel sorry for him," Weinberg said. "But I'm also furious. ... It's all that I've got to not get on an airplane and go to visit him in prison, and not sit across from him and just ask, 'Why, why would you do this?' "
