Police sergeant Mario Stewart was indicted on federal civil rights charges for using excessive force.
The alleged incident occurred in March 2019 when officers responded to a distressed and partially naked man.

Stewart pleaded not guilty and claims he was responding to a mental health call.
The mayor condemned the alleged conduct as eroding public trust in the police.
