From the Chicago Tribune:
State troopers responded to the area near I-57 and 111th Street after receiving several calls about a motorist driving the wrong way, authorities said.
The car, a 2010 Black Mitsubishi Outlander, had been traveling northbound in the southbound lanes, police said. The driver, Danny Sevilla, 33, stopped without incident, police said. Sevilla was the only person in the vehicle, police said.
Sevilla was charged with driving under the influence and driving the wrong way, state police said. No injuries were reported.
According to sources and records, Sevilla is a Chicago police officer who was hired in 2008.
In March, 2013, a North Chicago police officer was arrested after driving the wrong way on Lake Shore Drive and crashing into a Jeep, causing the death of two. That officer, Terrell Garrett, was sentenced to 10 years in prison.
