CHICAGO — Four black people were charged with hate crimes Thursday in connection with a video broadcast live on Facebook that showed a mentally disabled white man being beaten and taunted, threatened with a knife and forced to drink from a toilet.

The assault went on for hours, until Chicago police found the disoriented victim walking along a street, authorities said.

The suspects, who were jailed, can be heard on the video using profanities against white people and President-elect Donald Trump.

Police spokesman Anthony Guglielmi said investigators initially concluded that the 18-year-old man was singled out because he has “special needs,” not because he was white. But authorities later said the charges resulted from both the suspects’ use of racial slurs and their references to the victim’s disability.

The victim was a classmate of one of the attackers and initially went with that person voluntarily, police said.

“He’s traumatized by the incident, and it’s very tough to communicate with him at this point,” police Cmdr. Kevin Duffin said.

Excerpts of the video posted by Chicago media outlets show the victim with his mouth taped shut and slumped in a corner of a room. At least two assailants are seen cutting off his sweatshirt, and others taunt him off camera. The video shows a wound on the top of the man’s head. One person pushes the man’s head with his or her foot. A red band also appears to be around the victim’s hands. He was tied up for four to five hours, authorities said.

The victim does not appear to make any attempt to defend himself or to escape his attackers. He is a suburban Chicago resident described by Police Superintendent Eddie Johnson as having “mental health challenges.”

The case heighted political tensions on social media, with some conservatives suggesting it was linked to the Black Lives Matter movement. Police said there was no indication of any connection.

The incident began Dec. 31, when the victim and one of the suspects, 18-year-old Jordan Hill, met at a suburban McDonald’s to begin what both the victim and his parents believed would be a sleepover, police said.
