Chicago Police are investigating an apparent torture video found on social media showing a white man being taunted, battered and cut by a group of African-Americans who were smoking, drinking and laughing.

The suspected victim was found wandering disoriented on the West Side Tuesday evening.

Police spokesman Anthony Guglielmi said Wednesday four people are being questioned but no charges were immediately filed.

Police found the suspected victim wandering disoriented after responding to a battery call at a residence where they found signs of a struggle and property damage.

“Officers later became aware of a social media video depicting a battery of an adult male, which is believed to be the same individual [found wandering],” police said in a statement. “At this point CPD believes the video is credible and detectives are questioning persons of interest in the case.”

Police labeled the video “disturbing.”

The more than 27-minute video was live streamed on Facebook, WBBM-TV, Chicago, reported.

On it, at least four African-American men are seen drinking, laughing and smoking what appears to be marijuana as they torture a white man, who was cut and hit repeatedly while the assailants shouted, “F--- Donald Trump, nigga!” and “F--- white people, boy.” The victim’s mouth was taped shut, and he has a terrified look on his face and cut on his scalp.

The video was streamed by a young African-American woman identified as Brittany Herring, WFLD-TV, Chicago, reported.

Police in northwest suburban Crystal Lake, 48 miles from Chicago, identified the victim as a special needs, high-risk missing person. He had traveled to suburban Carol Stream to meet a friend and wound up in a stolen car in which he was transported to Chicago’s West Side.

The victim was hospitalized.

The incident is just one more in a violent start to 2017. Twenty-eight people were shot New Year’s Day and 12 more Tuesday, three fatally.
