Chicago police officer Gerald Callahan has received two years of probation for an allegedly unprovoked attack on patrons at a Niles bar in 2008.
The judge found Callahan, 42, guilty of misdemeanor battery in the May 17, 2008 attack on two bar patrons. Witnesses said he was unprovoked when he struck the 50-year-old woman and 61-year-old man. Callahan reportedly fled the scene, but was found passed out in bushes nearby.
He has a history of run-ins with the law during his 15-years on the force. Those include suspensions and a federal lawsuit.
2004: Callahan suspended for 16 days for being absent without permission
2004: Callahan accused of being intoxicated while off duty. City settles with bartender who was attacked after he stopped serving the officer for $15,000 out of court in 2006.
