Chicago police commander Glenn Evans pleaded not guilt at his arraigned Tuesday on police brutality charges as new details emerge about a long list of other complaints against him.
Evans is charged with official misconduct and aggravated battery.
Prosecutors say Evans shoved his gun down a man's throat, put a taser gun to his groin, and threatened to kill him.
The Chicago Tribune reports there have been 50 complaints against Evans since 2001 and nine complaints since he was promoted to commander of the South Side's Grand Crossing District in 2012.
His next court appearance is scheduled for October 23.
