Prince George's County police are looking for a man involved in an armed robbery in Largo.

About 1 a.m. on July 7, the robber approached the victim on Campus Way South at Harry S. Truman Drive and stuck a black revolver into the victim's back. The man ordered the victim to lie on ground, then demanded the victim's wallet.

The victim's credit card was used soon after at a Wawa convenience store in Capitol Heights, police said.
