BAY POINT -- Police have arrested a man in connection with a freeway shooting that landed two men in the hospital and snarled Highway 4 traffic during rush hour on Friday.

Daniel Hill, a spokesman for the California Highway Patrol, said Tuesday that one man had been arrested and jailed in connection with the 2:45 p.m. freeway shooting that followed a road rage incident. The suspect's name and age were not released.

Two drivers had a moving confrontation on the highway that resulted in gunfire and both continued driving. The CHP later received word that two men had been admitted to Contra Costa Regional Medical Center in Martinez with gunshot wounds.

Both men were later transferred to John Muir Medical Center in Walnut Creek, one with moderate injuries and the other with major injuries. Their conditions were not available Tuesday night.

A blue sedan with bullet holes has been impounded as evidence in connection with the incident, but investigators still seek a four-door red sedan, unknown make and model, with bullet holes on the right side. The driver of the sedan is also being sought.

The vehicle and driver were last seen last Friday about 3 p.m. at the Contra Costa Regional Medical Center. The driver who dropped the two off left without providing identification.

It was the second freeway shooting in a 24-hour span late last week. On Thursday afternoon, authorities closed westbound Interstate 580 between Highway 238 and the 164th Avenue exit after one driver fired on another in the adjoining lane. No one was injured in that incident. Alameda County Sheriff's deputies later tracked down and arrested four suspects in the shooting.

Anyone with information about either case is asked to call the CHP at 707-551-4100.
