Police were searching for a man on foot in Chester, Delaware County after the suspect hit a police officer and his car near Grace Street Thursday afternoon.
The man allegedly was stopped as part of a drug-related investigation around 2:30. During the stop, the suspect fled, hit the officer's car, then sped off.
The suspect bailed out of his car in a vacant lot and took off on foot a short time later.
Police and K-9 units searched the vacant lot and a nearby home, but lost the suspect and K-9s lost his scent after about a block, so search was called off.
The suspect abandoned his car near Mary Street, where police continued to investigate.
The officer whose police car was hit was not seriously injured.
