A driver was hospitalized Monday after striking a Shaler police vehicle en route to a car crash.

Shaler police were dispatched about 7 a.m. to Kittanning Street after a car flipped onto its side near the intersection with Badali Drive, Chief Sean Frank said.

Firefighters and paramedics extricated the driver, whom Frank did not name, and took him to a hospital.

The driver was the only person in the car, Frank said. Police do not know the extent of the injuries.

A police officer was responding to the crash when another motorist struck the police vehicle at Catherine Street and Route 8 in Etna, an intersection dubbed the Mae West Bend, Frank said.

The driver in the second crash also was hospitalized, Frank said. The officer was not injured.
