An on-duty Chicago Police officer was charged with DUI on Tuesday afternoon in the parking lot of a police station in the Southwest Side Chicago Lawn neighborhood.

Dale Jesionowski, 53, was driving a police vehicle around noon in the 8th District police station parking lot at 3420 W. 63rd St. when he struck a curb, according to a statement from Chicago Police spokesman Anthony Guglielmi.

An on-duty police lieutenant witnessed the crash and had a conversation with Jesionowski, who was charged with one misdemeanor count of DUI, police said.

Jesionowski, who is assigned to the 8th District, has been relieved of his police powers while Internal Affairs investigates, police said. “These allegations are serious and the district took appropriate steps,” Guglielmi said.
