A police officer and a group of passers-by helped free two men from a car that plunged into a canal and flipped over early Saturday in central Modesto. The driver suffered injuries, but they did not appear to be life-threatening, said Modesto Fire Battalion Chief Terry Inderbitzen. Both men were taken by ambulance to a local hospital. The car went into the canal where it intersects with Magnolia Avenue. The Modesto police officer jumped into the canal and was followed by about six passers-by. All of them helped pull the driver and the passenger out of the car, said Modesto police Lt. Ron Cloward.
