From [HERE] and [HERE] A man filed a lawsuit against the city and the Chicago Police Department Thursday, after video showed police using force to detain him as he was arrested earlier this week. 

The man—Lorenzo Williams, 32—was charged with felonies and misdemeanor after his arrest Tuesday in the Cabrini Rowhouses, in the 800 block of North Cambridge Avenue on the Near North Side. 

In the video, a man now identified as Williams is seen on the ground, surrounded by police officers. Three of the officer are trying to detain him—with one holding him by the braids of his hair, and another hitting him in the head with what appears to be a police radio and then saying, "I'm going to shoot you." 

This officer then pulls out his weapon and holds it to Williams' head. The video then ends.

The lawsuit filed today by Williams and his attorney alleges illegal use of force—claiming Williams was "peacefully walking on public property" when he was approached by officers. 

But the police report for the incident says otherwise. The report said officers were monitoring POD camera video in the area of Cambridge Avenue and Iowa Street—which is known for its gang and drug activity—and saw Williams with the butt end of a handgun in his front middle waistband as he lifted his shirt up.
