The occupants of a Cadillac shined a laser into officers' eyes, prompting the police to initiate a traffic stop, police said. But the driver led police on a 10-mile (16-kilometer) chase to the city of Hercules, where the driver and three occupants bailed out of the vehicle.
Inside the vehicle, police found the 10-foot (3-meter) python. The driver was arrested on multiple charges, including felony evading. The passengers received misdemeanor citations.
Vallejo is about 30 miles (5-0 kilometers) northeast of San Francisco.
