The NBA’s Sterling Brown, who was tased and arrested earlier this year after an altercation stemming from a parking violation, filed a lawsuit Tuesday against the city of Milwaukee, the police chief and the eight officers involved in his arrest.

Key to the suit will be one of the officers’ alleged social media posts, which appear to celebrate the actions of the officers, three of whom were suspended without pay. Though an initial police report described Brown as aggressive, Police Chief Alfonso Morales has since apologized for the officers’ behavior, saying they acted “inappropriately.” Mayor Tom Barrett said, “No citizen should be treated this way.”

The lawsuit alleges, among other things, unlawful arrest, excessive use of force and violation of the 14th Amendment’s Equal Protection Clause. It also accuses the officers of collaborating to conceal their actions. It seeks compensatory and punitive damages, stating that Brown suffered “unnecessary and severe personal physical and psychological and emotional injuries.”

Read the complaint for yourself

According to the lawsuit, in addition to discriminating against Brown because he’s black and violating his rights by treating a parking violation as a criminal offense, officers also failed to read Brown his Miranda rights. Also, at certain points some of the officers turned off their bodycams, the suit says.

Photos included in the lawsuit show the injuries Brown allegedly suffered at the hands of police.

It also accuses one of the officers, Sgt. Jeffrey Krueger, of firing his Taser on four previous occasions “that did not result in charges being brought against his victims.”

“For too long, African-American men have been arrested and abused and killed as a result of bad police work,” Brown’s attorney, Mark Thomsen, said. “That work is a stain on this city and an insult to good police officers in this city and county.”

Reached for comment, the Milwaukee Police Department said Morales will review the incident during a Thursday morning meeting “and will be available for comment afterward.”

The altercation began when the Milwaukee Bucks shooting guard exited a drug store early January 26 to find an officer – identified in the lawsuit as Officer Joseph Grams – outside his car, which was parked across two handicapped parking spots.

It quickly escalated after Grams shoved Brown and Brown told the officer not to touch him. Grams called for backup and seven officers responded, according to the lawsuit and bodycam video released earlier this month.

Officer’s Facebook posts

Tuesday’s lawsuit singles out Officer Erik Andrade, one of the responding officers – not so much for his actions during the arrest, but for his social media posts after the incident.

Some of those posts mocked Brown, according to the lawsuit:

  • “Nice meeting Sterling Brown of the Milwaukee Bucks at work this morning! LOL #FeartheDeer,” Andrade wrote on Facebook, referencing the Bucks’ rallying cry.
  • Responding to a shared story about Brown’s arrest – which tagged Andrade and said, “let the man get his early morning craving of popcorn” – Andrade responded with a laughing emoji.
  • In response to another post from someone saying they wanted Andrade’s autograph because Andrade was featured in a YouTube video of Brown’s arrest, Andrade responded, “I didn’t arrest him lol.”
  • Andrade also shared a post showing three pictures of black men, including Brown, that said, “Yes, whenever something happens it’s always a epidemic of racism, police brutality or whatever lies these failed liberal hand picked so-called liberal black leaders come up with.” Above the post, Andrade wrote, “A little truth to those who wanna listen.”
  • After Game 1 of the NBA Finals, during which the Cleveland Cavaliers’ J.R. Smith committed a gaffe by letting the time run out when the game was tied, Andrade posted on Facebook, “I hope JR Smith double parks in Walgreens handicap parking spots when he’s in Milwaukee.”

Of the Smith post, the lawsuit says, “Defendant Andrade’s post is an admission that he and other Defendant officers are allowed to engage in unlawful attacks and arrests of African Americans without justification and then relish such events without any fear of real discipline.”

(CNN) In January, Milwaukee Bucks rookie Sterling Brown was tased and arrested after police say he became confrontational over an alleged parking violation. Now the city's mayor says he is concerned about soon-to-be-released police body camera video of the encounter. Brown was not criminally charged in the incident, which prompted an internal affairs investigation, authorities said at the time. According to a police report obtained by CNN affiliate WISN, Brown was aggressive when a police officer questioned him in a Walgreens parking lot and then resisted arrest. Four months later, Milwaukee police are bracing for a possible backlash from the expected release of body camera footage of the encounter with Brown, then 22, early on January 26. At least two officers were involved in the incident.

The lawsuit also alleges Andrade made other insensitive and racially charged posts:

  • Andrade wrote, “Damn…..more naps than a preschool! Lmao” above a photo of an ice cream cone with chocolate sprinkles juxtaposed with an image of the back of NBA superstar Kevin Durant’s head. The caption reads, “Who wore it better?”
  • “What comes to mind when I’m at work and I’m driving down Greenfield Ave. smh,” Andrade wrote in one post, which featured a graphic that said, “Sick and Tide of these hoes” and featured the logo for Tide laundry detergent. Greenfield Avenue is a prostitution hub in Milwaukee.
  • Andrade seemed to celebrate using force in one post, saying, “Had great time workin replacement over in D5 the other day….5+ OT and a use of force. Lol.”
  • In a May 3 post about a man fighting with Milwaukee police, Andrade wrote, “Let’s see the whole video now since people are cryin police brutality and how officers are beating an innocent black man for no reason. You social media educated fools are too much sometimes.”
  • In response to a news story about Milwaukee enacting a policy against mass incarceration, Andrade wrote, “It’s hilarious when people talk about mass incarceration lmao like wtf is that???? Mostly all the people I deal with at work do not stay locked up when they should be. Last time I checked if you don’t commit crimes you don’t get incarcerated.”

Two sets of bodycam footage

The Milwaukee Police Association initially defended the officers who arrested Brown, calling use of force “a necessary component of policing” and slamming city leaders for failing to defend the officers.

After a batch of bodycam footage was made public this month, the union softened its tone, saying it welcomes “appropriate review and oversight” of the matter.

The first bodycam footage, released in May, contradicted the initial police account and showed the situation escalated into a testy confrontation in a matter of seconds.

Brown, who was 22 at the time, and an officer approach each other. While asking the Bucks rookie for his license, the officer tells Brown to back up and lightly shoves him immediately upon giving the command. After Brown tells the officer repeatedly not to touch him, the officer calls for backup, prompting at least three more squad cars to descend on the scene.

Sterling Brown was drafted out of Southern Methodist University with the 46th pick in the 2017 NBA Draft.

Multiple officers surround Brown at his car and ask him questions. At one point, an officer yells at Brown to take his hands out of his pockets, and Brown says he has “stuff” in his pocket. Other officers grab the athlete and pull him to the ground before he’s tased. Brown groans from the shock.

The second batch of footage was released earlier this month and shows an officer stepping on the subdued Brown’s ankle during his arrest, despite his legs lying motionless on the ground after he was tased. It also shows other officers mocking the NBA player.

At one point, according to the lawsuit, Grams, who initiated the stop, can be heard saying to himself, “What is wrong with these people, man?”

Ten of the 15 aldermen on the Milwaukee Common Council expressed concern that the second batch of footage was not included among video shared with the council two months prior. They demanded transparency, as well as “swift and appropriate action to all those involved who violated MPD policies and procedures,” the aldermen’s open letter said.

Brown was issued a parking ticket but was not charged with a crime after the incident. Hours later, sports reporters said Brown had a bruise and scab on his face before a game that night against the Brooklyn Nets.

Officers suspended

The incident prompted an internal affairs investigation. Two sergeants were suspended without pay – for 10 and 15 days, respectively – for “failing to be a role model for professional police service,” while another officer was suspended for two days for “failing to treat a member of the public with courtesy and professionalism.”

Eight others will receive remedial training in professional communications, officials said.

The Milwaukee Bucks said the officers’ actions were shameful and inexcusable.

“It shouldn’t require an incident involving a professional athlete to draw attention to the fact that vulnerable people in our communities have experienced similar, and even worse, treatment,” the team said.

Brown released a statement, he said, on behalf of Laquan McDonald, Stephon Clark and others in the black community who have been killed during police encounters.

“The common denominator in all of these situations has been racism towards the minority community, the abuse of power and the lack of accountability for officers involved,” he said in the statement.

Milwaukee police were so concerned about the initial release of bodycam footage last month that, before its release, Assistant Police Chief Michael Brunson told parishioners of a Milwaukee church that the department was bracing for backlash.

“There’s going to be a video that’s going to come out soon, in the next couple of weeks, involving the department,” said Brunson, according to CNN affiliate WITI. “And I’m going to be honest with you, we’re going to need your support during the challenges.”
