Chicago Police Thursday filed hate-crime charges against four people who attacked a mentally disabled suburban man while screaming obscenities against Donald Trump, white people and the victim’s mental capacity in a live stream posted on Facebook.

Police Superintendent Eddie Johnson described the video as “sickening.”

"The actions on that video were reprehensible," Johnson said, adding racism has no place in the city.

“It makes you wonder what would make individuals treat somebody like that. I’ve been a cop for 28 years and I’ve seen things you shouldn’t see. It still amazes me how you still see things you just shouldn’t.”

Charges of aggravated kidnapping, hate crime, aggravated unlawful restraint and aggravated battery with a deadly weapon were filed against Jordan Hill, 18, of Carpentersville, Tesfaye Cooper, 18, of Chicago, Brittany Covington, 18, of Chicago, and her sister, Tanishia Covington, 24, of Chicago.

Additional charges of robbery, possession of a stolen motor vehicle and residential burglary were filed against Hill. Cooper and Brittany Covington also were charged with residential burglary.

The four were scheduled to appear in bond court Friday.

The Chicago Sun-Times reported Tanishia Covington is the only one of the four with an adult criminal record. She was convicted of shoplifting in 2015. Charges of assault and battery filed in 2009, 2012 and 2014 were later dismissed. Shoplifting charges were filed against Brittany Covington in October but were dismissed.

Hill and the 18-year-old victim had attended the same school in Aurora, but police said it was unclear whether that was recent.

The video shows the victim, who was held for 24 hours, cowering in a corner, his mouth taped shut and his wrists bound. The attackers can be seen slashing at his clothing with knives, punching him and stomping on his head. Police said the victim was scalped.

While the attack is taking place, the attackers can be heard shouting “F--- Donald Trump” and “F--- white people.” Someone also tells the victim: “Kiss the floor, b-------!” and “Nobody can help you anymore.” Someone also orders him: “Say, ‘I love black people.’ “

“The disturbing images on this video demonstrate a level of depravity that is an outrage to many Americans,” said White House spokesman Josh Earnest, who added he has not yet discussed the incident with President Barack Obama.

Police spokesman Anthony Guglielmi said it was more likely the victim, who was found wandering and disoriented, wearing an inside-out tank top, shorts and sandals despite the temperature, by police Tuesday evening, was targeted because of his disability than because he is white, the Chicago Tribune reported. He was taken to a hospital for treatment. Police described the victim as traumatized but declined to elaborate on other possible injuries. He was in his parents’ custody Thursday.

“They [officers] saw clearly that this individual was in distress and he was in crisis. And they cared enough to do something about it,” Police Capt. Steven Sesso told the Sun-Times.

Police said Thursday the victim met Hill at a McDonald’s in Streamwood. The two occasionally hung out together. While the victim was at McDonald’s, Hill allegedly stole a van and then the two drove to Chicago’s West Side where the victim, who did not know the van was stolen, slept in the vehicle.

The next morning he and Hill went to the Covingtons’ apartment where they engaged in a play fight that escalated. The women were aggravated by the horseplay, police said, and tied him up.

The video shows the attackers smoking what appear to be cigars. Police said they presume they were marijuana blunts.

Police were summoned by a downstairs neighbor complaining about the noise. Police said two of the suspects, upset officers were called, barged into the neighbor’s apartment and committed burglary as the victim escaped.

Police said officers found “signs of a struggle and damage to property [in the Covingtons' apartment] and were able to link this evidence to the disoriented male.”

The victim was reported missing by his parents Monday. Streamwood Police said the parents had received text messages indicating the victim was being held captive.
