The man suspected of stabbing renowned author Salman Rushdie in western New York pleaded not guilty Saturday to attempted murder in the second degree and other charges, his attorney says.

Hadi Matar, 24, is accused of stabbing Rushdie – whose controversial work has triggered death threats – at a speaking engagement on Friday, authorities said.

Matar, a New Jersey resident, also was charged with assault in the second degree, with intent to cause physical injury with a deadly weapon. Matar pleaded not guilty, according to Nathaniel Barone, his public defender. The attorney said Matar has been “very cooperative” and communicating openly, but he did not discuss the content of those conversations.

He was refused bail and remanded to the Chautauqua County Jail. Matar’s next court appearance is Friday.

Rushdie, 75, was stabbed on stage at the Chautauqua Institution before he was slated to give a lecture, New York state police said Friday. He was airlifted to a hospital in northwestern Pennsylvania and underwent surgery, a Pennsylvania police official said. The hospital said it had no update to provide on his condition Saturday.

Rushdie’s injuries included three stab wounds to the right side of the front of his neck, four stab wounds to his stomach, a puncture wound to his right eye, a puncture wound to his chest, and a laceration on his right thigh, according to Chautauqua County District Attorney Jason Schmidt, who provided details of the injuries during Matar’s arraignment.

Rushdie may lose his right eye, the county prosecutor added.

On Friday, Rushdie was put on a ventilator and was unable to speak, his agent, Andrew Wylie, told The New York Times. “The nerves in his arm were severed; and his liver was stabbed and damaged,” Wylie said. “The news is not good.”

The FBI is working with local and international authorities in its investigation into the attack, including “international partners in the United Kingdom to provide additional resources, since the victim is a UK-US dual citizen,” a spokesperson told CNN on Saturday.

Suspect described as ‘quiet’ and keeping to himself

The attack occurred around 10:45 a.m. as Rushdie was being introduced, a witness told CNN. A man in a black shirt appeared to be “punching” the author. The witness, who was about 75 feet from the stage, did not hear the attacker say anything or see a weapon.

Another witness, Joyce Lussier, was sitting in the second row when she saw a man leap across the stage and lunge at Rushdie. She heard people screaming and crying and saw people from the audience rushing up to the stage, she said. Staff and audience members rushed to the attacker and put him on the ground before a state trooper took him into custody, police said.

A witness who asked not to be named and said they saw the attack captured photos of the suspect being detained. The owner of a boxing gym where Matar was a member confirmed the photos are of Matar. And the suspect’s attorney also verified to CNN the photos appear to be his client.

Photos of Hadi Matar were captured by a witness moments after the attack.

The witness told CNN they were among those who rushed on stage after the attack to offer help and then went outside where they captured the photos of Matar.

The witness said there were medical professionals from the audience who also rushed to help. “I have no training that would have helped,” the witness added. “I was just operating on adrenaline and instinct.”

On Friday evening, police had blocked off the street to the New Jersey home believed connected to the suspect.

Matar frequented a boxing gym in North Bergen, New Jersey, where members say he was quiet and mostly kept to himself. CNN exclusively spoke with State of Fitness Boxing Club owner Desmond Boyle, who said Matar enrolled at the gym in April.

“You know that look, that ‘it’s the worst day of your life’ look? He came in every day like that,” Boyle told CNN on Saturday.

Roberto Irizarry, a member of the gym, told CNN Matar frequented the gym about three or four times a week and was “a very quiet kid.”

“It’s a brotherly environment, family environment – we try to involve everybody. He was to himself, pretty much,” Irizarry said.

Questions raised around security precautions

Following the attack, questions were raised about the security precautions – or lack thereof – at the host institution, which sits in a rural lake resort about 70 miles south of Buffalo, New York.

The institution’s leadership had rejected recommendations for basic security measures, including bag checks and metal detectors, fearing that would create a divide between speakers and the audience, according to two sources who spoke with CNN. The leadership also feared that it would change the culture at the institution, the sources said.

The two sources have direct knowledge of the security situation at the Chautauqua Institution and past recommendations and spoke to CNN on condition of anonymity because they were not authorized to speak publicly.

It’s unclear whether the recommended measures would have prevented the attack on Rushdie based on the information released about the incident as of Friday evening. Authorities have not disclosed the type of weapon that was used in the attack.

There were no security searches or metal detectors at the event, a person who witnessed the attack told CNN. The witness is not being identified because they expressed concerns for their personal safety.

CNN reached out to the Chautauqua Institution and its leadership for comment but did not receive a response Friday.

Institution president Michael Hill defended his organization’s security plans when asked during a news conference Friday whether there would be more precautions at future events.

“We assess for every event what we think the appropriate security level is, and this one was certainly one that we thought was important which is why we had a State Trooper and Sheriff presence there,” Hill said. “We will assess for each of the events at the Institution what we think the appropriate level of security is and that’s an ongoing process that we work in concert with local law enforcement on.”

The suspect arrived in Chautauqua at least a day before the event and bought a pass to the event two days prior, Schmidt said during Matar’s arraignment.

Matar traveled to Chautauqua by bus and had cash, pre-paid Visa cards and false identification with him, Schmidt added.

“This was a targeted, pre-planned, unprovoked attack on Mr. Rushdie,” Schmidt said.

Both Schmidt and Barone, the suspect’s public defender, said Matar has no documented criminal history.

An Iranian leader had called for Rushdie’s death

Also injured Friday was Henry Reese, co-founder of the Pittsburgh nonprofit City of Asylum, who was scheduled to join Rushdie in a discussion, police said. He was taken to a hospital and treated for a facial injury and released.

The world reacts to attack on Salman Rushdie

Reese is on the advisory committee for press freedom group PEN America, which tweeted a message from him late Friday: “Salman Rushdie is one of the great authors of our time and one of the great defenders of freedom of speech and freedom of creative expression.”

Reese added, “We revere him and our paramount concern is for his life. The fact that this attack could occur in the United States is indicative of the threats to writers from many governments and from many individuals and organizations. In addition to wishing Salman well as Americans and citizens of the world, we need to re-commit ourselves to defending the values Salman has championed.”

US President Joe Biden said in a statement he was saddened by the attack.

“Salman Rushdie — with his insight into humanity, with his unmatched sense for story, with his refusal to be intimidated or silenced — stands for essential, universal ideals. Truth. Courage. Resilience. The ability to share ideas without fear. These are the building blocks of any free and open society,” Biden said.

Rushdie’s writings have garnered several literary prizes, including the Booker Prize for his 1981 book, Midnight’s Children. But it was his fourth novel “The Satanic Verses,” that drew the greatest scrutiny as some Muslims found the book to be sacrilegious, and its publication in 1988 sparked public demonstrations.

The late Iranian leader Ayatollah Ruhollah Khomeini, who described the book as an insult to Islam and Prophet Mohammed, issued a religious decree, or fatwa, calling for Rushdie’s death in 1989.

Iran’s bounty was never lifted

Rushdie, the son of a successful Muslim businessman in India, was educated in England, first at Rugby School and later at the University of Cambridge where he received a master’s degree in history.

After college, he began working as an advertising copywriter in London, before publishing his first novel, “Grimus” in 1975.

In 1989, as a result of the fatwa, Rushdie began a decade under British protection.

Rushdie told CNN in 1999 that the experience taught him “to value even more … intensely the things that I valued before, such as the art of literature and the freedom of expression and the right to say things that other people don’t like.

“It may have been an unpleasant decade, but it was the right fight, you know. It was fighting for the things that I most believe in against things I most dislike, which are bigotry and fanaticism and censorship.”

The bounty against Rushdie has never been lifted, though in 1998 the Iranian government sought to distance itself from the fatwa by pledging not to seek to carry it out.

Despite that, Iran’s Supreme Leader Ayatollah Ali Khamenei recently reaffirmed the religious edict.

In February 2017, on Khamenei’s official website, the supreme leader was asked if the “fatwa against Rushdie was still in effect,” to which Khamenei confirmed it was, saying, “The decree is as Imam Khomeini issued.”
