(Portland, OR) -- Police blocked off a northwest Portland neighborhood Thursday afternoon as they searched for a suspect in an armed robbery. A woman called 911 after a man she knew broke into her apartment and robbed her at gunpoint. He ran from the scene. The woman told police the man lived in a nearby tent. Officers closed several streets around the area and told residents to shelter inside. They saw movement inside of the tent, but after using a robot to cut it open they learned it was a dog inside of the tent. The suspect was gone and hasn't been arrested.
