(Portland, OR) -- A man is facing charges after allegedly breaking into a home in North Portland. It happened last Thursday night on Overlook Terrace. The Portland Police Bureau says Timothy Lawrence broke into a home and threatened to kill the person inside. He then allegedly hit a police officer in the face with a rock while they were trying to arrest him. Lawrence is known to police. Officers arrested him just three days before Thursday's incident for allegedly making threats and exposing himself to children at Blue Lake Park.
