PHILADELPHIA (CBS) — Philadelphia Police say a man was shot and killed by a person he was trying to rob in the Strawberry Mansion section of the city on Tuesday morning. The shooting happened on the 2600 block of North Napa Street, shortly before 10 a.m.

Police sources say the shooter is a city employee, working as a victim services advocate for the District Attorney’s Office.

Police say when the 31-year-old man tried to rob the city employee at gunpoint, he pulled out his own weapon and fired, striking the would-be robber in the chest.

The man was pronounced dead at the scene.

No charges have been filed.

Eyewitness News reached out to the District Attorney’s Office and a spokesperson says that this is an active investigation that has been referred to another agency, and declined to give additional comment.
