Protesters became “unruly” as they approached the station at 3151 W. Harrison about 7:45 p.m. and started to climb onto parked squad cars, according to a statement from Chicago Police.

Police said the girl began jumping up and down on the roof and trunk of an unmarked squad car, causing damage to the car.

As officers tried to remove the girl from the top of the car, 33-year-old Shimron Robinson approached them from behind and “lowered his shoulder, knocking an officer to the ground,” police said. Robinson and the girl were taken into custody and walked into the station for processing.
