A man with a firearm was shot dead by a police officer at an Alexandria, Virginia, apartment building Monday night.

The Alexandria Police Department said officers received “a call for service” at 5101 Maris Ave. at about 10:46 p.m.

When officers arrived at the Alexandria Overlook apartments, police said they were “met in the stairwell by an adult male armed with a firearm.”

A neighbor told WTOP that he heard those officers shout at the man to drop the gun. He later heard several shots fired.

Police said “the encounter resulted in an officer-involved shooting,” and the man was pronounced dead on the scene. There were no injuries.

The man has yet to be identified.
