WEST DEPTFORD TWP. — Seven high-caliber rounds were fired at the police station at about 4:05 a.m. Tuesday in what police say appears to be a drive-by shooting.

An officer inside the station heard the gunfire outside, according to authorities. He cautiously went outside and went around the building to see five rounds had hit the front door. One round hit a the north-facing wall of the building, where police cars are parked.

The seventh round went through the window of Deputy Chief Sean McKenna's office.

No one was injured.

Security video shows a black sedan speeding through the parking lot twice, but police have not yet determined if the shots were fired on the first pass or the second, said authorities.

The rounds appear to be at least .40-caliber or higher, authorities said.

Investigators are trying to get the video enhanced so they can perhaps read the license plates on the black sedan.

The police station shares the building with municipal offices.
