FREMONT -- A man shot at least three times during a road-rage incident in Fremont on Thursday was released from the hospital hours after undergoing emergency surgery, officials said.

The 59-year-old Pleasanton man, whose name has not been released, was discharged after a successful operation on a bullet wound to his abdomen, an injury he suffered when he crossed paths with an armed motorist on Interstate 680.

Officials say the victim was shot by a man in a newer-model white car with large, polished chrome rims.

Although authorities do not know how the dispute escalated, they believe it may have started because the victim was driving slowly in the fast lane.

No arrests have been made in the incident, which began on southbound I-680 near Washington Boulevard and prompted both drivers to exit the freeway at Mission Boulevard and turn right onto Brown Road, Fremont police spokeswoman Geneva Bosques said.

The suspect, who is wanted for attempted murder, fired at least four shots at the victim as he sat with his dog in his brown Mercedes, shattering the driver's side window and riddling the door with bullet holes.

One of the shots hit the man in the upper torso, and at least two more caused wounds that were less serious, Bosques said. The man's aging German shepherd was not hit by the gunfire.

After the shooting, the victim drove to the Donut House in the 46600 block of Mission Boulevard, where a customer saw that he was badly wounded, prompting an employee to call police. Rescue crews took the man to a hospital.

The shooting was the second case of violent road rage in Fremont in eight days.

On Oct. 17, a man fired shots at a car whose driver honked at him near the intersection of Auto Mall Parkway and Technology Drive.

"I'm not going to say Fremont is a dangerous place to drive," Bosques said. "We have a lot of major thoroughfares running through our city. (Interstates) 680 and 880 (and Highways) 237 and 84 all travel through our town and are heavily traveled, and for these kinds of incidents to escalate to a shooting is beyond reason."

Anyone with information about the suspect or the incident is asked to call Fremont police at 510-790-6900.
