(STMW) — Chicago Police Supt. Eddie Johnson has asked the Independent Police Review Authority to open an investigation Monday after a newly posted video appeared to show an officer stomping a man’s head as another officer tried to arrest him.

The video, posted to Facebook, appears to show an officer struggling to arrest a man in the 3900 block of West Grenshaw. Another officer pulls up and orders onlookers to step back. He then radios for assistance before walking over to the man on the ground — who was still trying to get away — and apparently kicking him in the head.

After the kick, several other people took their cellphones out to record the incident and photograph the officer’s squad car.

One person yelled: “Y’all gonna die. Y’all gonna end up dead.”

In an email Monday night, Chicago Police Department spokesman Anthony Guglielmi said Johnson has asked IPRA to open an investigation into the incident.

Guglielmi added that the Chicago Police Internal Affairs Division “is preparing a briefing for the superintendent concerning the officer’s status.”

As of 9:30 p.m. Monday, the video had been viewed more than 260,000 times.
