OAKLAND, Calif. -- Authorities say a man who was armed and wearing a bulletproof vest was hospitalized Sunday after he opened fire on two California Highway Patrol officers during a traffic stop on an Oakland freeway.

The trouble began early Sunday when the officers pulled over the driver of a car that was speeding and weaving on Interstate 580, said CHP Sgt. Trent Cross.

Cross said the driver, who was armed with a high-powered rifle, a shotgun and a handgun, opened fire on the officers.

The officers returned fire, hitting the suspect multiple times.

Investigators on Sunday were still trying to determine the number of shots fired, though Cross said the exchange "lasted for a few minutes."

The suspect, identified only as a 45-year-old Groveland man, was hospitalized in stable condition at a local hospital.

The two officers, who have not been identified, suffered minor injuries from flying glass.
The shooting prompted the closure of Interstate 580 around 1 a.m. while police investigated.

CHP said all westbound lanes of Interstate 580 near Grand Avenue in Oakland remained closed early Sunday afternoon while the investigation continued.

The freeway shootout came less than a day after Oakland and Bay Area Rapid Transit police officers shot and killed a man after they said he ran from officers and then charged at them while holding two knives.

Both incidents are being investigated by Oakland police and additional agencies.
