Police in California say General Motors' OnStar communications system stopped a dangerous high-speed chase and helped them capture a carjacking suspect by disabling a stolen sport utility vehicle.
OnStar officials say the incident early Sunday in Visalia was the first time the system was used to halt a chase.
Police say it all began about 3 a.m. when a 21-year-old man used a sawed-off shotgun to take a Chevrolet Tahoe from two men in a parking lot.
Police contacted OnStar, which found the Tahoe by using a global positioning system. Two officers spotted the SUV but the driver sped off. That's when OnStar operators sent a signal that slowed the Tahoe to a halt.
The surprised thief ran off but was quickly captured when he fell into a backyard swimming pool.
