A Prince George’s County police officer is under investigation after firing his weapon in the district.

The Prince George’s County Police Department said the incident happened after a police chase in Prince George’s County.

Around 4:30 p.m., Wednesday afternoon, the department’s officers responded to Urn and Nova streets in Capital Heights after receiving calls about a man firing a weapon.

A PGPD spokesperson said when officers got to the scene, they saw the suspect driving a black Mercedes Benz. Police say officers then chased the suspect into Southeast DC after failing to get him to stop in the county.

The suspect eventually did stop along the 5200 block of Southern Avenue, but not before police say he backed up into a PGPD officer’s cruiser.

PGPD police say officers then tried to arrest the man, but when they approached him, they spotted a gun in his lap.

PGPD Spokesperson Jennifer Donelan says an officer then yelled “there’s a gun”. After that, Donelan said an PGPD officer’s gun went off.

Donelan says the case is being investigated by DC Police since it happened in the district.

No one was injured in the incident. The officer was placed on administrative leave.
