Contra Costa County sheriff's deputies are looking for a man who may be trying to kidnap a young girl in Bay Point.
Investigators released a sketch of the man they believe approached four girls in the past week near the Riverview Middle School.
Witnesses say he was driving a red full-sized pick-up truck with no plates.
Investigators say he's exposed himself once and tried to lure some of the girls closer by asking for directions.
So far, nobody has been harmed.
