CHICAGO (CBS) — Two Chicago Police officers were hurt overnight, when their squad car flipped over as they responded to a call on the city’s Southeast Side.

The officers were headed out around 10:05 p.m. Tuesday to help another team of officers, who were chasing a stolen van in the 11000 block of South Avenue C, just a couple of blocks from the Indiana state line, police told the Sun-Times Media Wire.

Their squad car spun out of control, hit a parked car, and flipped over near the 100th Street bridge over the Calumet River.

South Chicago District police tell the wire the squad car slid on the wet pavement.

Police later recovered the van near 110th Street and Avenue C, but the driver had already bailed from the van and fled, police told the wire. The driver was not in custody as of early Wednesday.

The officers both suffered minor injuries. They were treated and released from Advocate Christ Medical Center in Oak Lawn for neck and back pain, the wire reported.
