US actor Jussie Smollett staged a fake attack on himself because he was “dissatisfied with his salary”, according to Chicago Police.
Police Superintendent Eddie Johnson said in a news conference that he “took advantage of the pain and anger of racism to promote his career”.
Mr Smollett is charged with filing a false police report after he said he was the victim of a homophobic attack.
Police say he also had sent a racist letter to himself at a Fox studio.
The 36-year-old actor is suspected of paying two Nigerian brothers to stage the attack. They are both co-operating with the investigation, police say.
On Wednesday his lawyers said they would “mount an aggressive defence”.
What do police say?
Suspicion over the actor’s claim started to grow after police said they could not find any video footage of the alleged incident from surveillance cameras. There were also no witnesses.
But investigators managed to track two men who appeared on video footage near where the actor said he had been attacked.
The men – Ola and Abel Osundairo – had left the US following the alleged attack and were held for nearly 48 hours after they returned last week.
They were released without charges after providing information that “shifted the trajectory of the investigation”, police said.
One of the brothers is Mr Smollett’s personal trainer and both have worked as extras on Empire.
On Wednesday, CBS Chicago obtained footage which appeared to show two people buying materials, including ski masks, that had allegedly been worn by the actor’s attackers.
Mr Smollett turned himself in early on Thursday and is in custody of Chicago police, spokesman Anthony Guglielmi said.
What does Smollett say happened?
The actor, who is gay, said he had gone out to buy food late at night in downtown Chicago when two white men hurled racial and homophobic insults at him.
They allegedly punched the actor, poured a chemical substance over him and put a rope around his neck.
Mr Smollett also claimed the men had told him “this is Maga country”, apparently referring to President Donald Trump’s “Make America Great Again” slogan.
The actor said he had been “forever changed” by the alleged incident. An outpouring of support followed, including from Oscar winner Viola Davis and supermodel Naomi Campbell.
