(Portland, OR)  --  Portland police have a man in custody after he was accused of stealing a vehicle that was left idling.  The owner of the Toyota 4Runner told police he left it running so he could leave on the air-conditioning to cool the vehicle down.  Authorities say San Saechao jumped into the vehicle and fought off the owner, who tried to intervene.  The car was found abandoned about six blocks away, and police say Saechao was tracked down at his home and arrested.  The owner of the vehicle suffered minor injuries.
