Police in San Francisco locked down a busy bridge to pursue a tiny dog who was on the run.
Dash cam footage from a patrol car shows a police officer on a motorcycle pursuing the small black chihuahua who is running down the westbound lane on the San Francisco-Oakland Bay Bridge.
California Highway Patrol posted footage of the incident which temporarily brought traffic to a near standstill.
In the footage the small dog appears to roam the bridge freely, racing across the lanes.
