In the video posted online Tuesday, a young white man is seen restrained, his mouth covered with duct tape as he sits on the ground. A young black man holding a knife cuts his clothing as well as his scalp.
“Fuck Donald Trump, fuck white people,” the man says.
The four people taken into custody are expected to be charged, Chicago police said at a news conference. Police Superintendent Eddie Johnson said the treatment of the young man, who he described as having “mental health challenges,” was sickening.
Johnson said police were investigating if the incident was a hate crime, but so far he said there was no indication it was motivated by politics or race.
“Some of this is just stupidity,” he said. “People just ranting about something they think might make a headline. We’ll keep investigating, and we’ll let the facts guide us on how this concludes.”
