An off-duty Chicago Police officer was grazed by a bullet early Sunday on the city's South Side, authorities said.
Around 5 a.m., the officer had completed his overnight shift and was driving westbound on West 31st Street near South Loomis Ave in the city's Bridgeport neighborhood, Chicago Police spokesperson Anthony Guglielmi said in a statement.
He saw a brown mini van speed up behind him, and slowed down to let the vehicle pass, authorities said. As the van pulled alongside the officer's car, someone inside the van pointed a gun in his direction and opened fire.
The officer suffered a graze wound to the upper left arm, according to police, and returned fire as the offenders fled the scene.
The officer was taken to Northwestern Memorial Hospital in good condition, police said, and he was expected to be treated and released.
The motive for the shooting is unclear, police said, though officials are not ruling out the possibility that the officer was targeted.
No one is in custody for the shooting, and authorities continue to investigate.
