A shooter opened fire early Tuesday on the building housing the West Deptford Police Department, pock marking it with seven bullets, but causing no injuries.
Police said they believe they were the intended targets of the drive-by shooting.
A police supervisor was in the building when the gunfire erupted, forcing the officer to take cover while calling for help, authorities said. Patrol cars arrived in 20 seconds, but there was no sign of the shooter's vehicle.
A high caliber weapon - .40-caliber or larger - had been used, police said. Five bullets went through the door officers use to get to the parking lot and one went into a police administration office.
