Thursday afternoon police started looking for a suspect in what appears to be an attempted robbery on Interstate 680.

Contra Costa County Sheriff's deputies found a vehicle on the Arthur Road on-ramp in Pacheco. The driver said he stopped to get something he dropped under the seat.

When he got out, he says, a man came up, drew a gun, and fired a shot that busted one of the car's windows. The driver has minor wounds.

Police were unable to find the gunman.
