A Pittsburg-Baypoint train was held for 9 minutes during the investigation of a man-with-a-gun call. A 29-year-old man was arrested for public intoxication. According to other patrons, he'd frightened them with his loud talk of having a gun. No weapon was actually seen by patrons. The suspect was booked into the Martinez Detention Facility and his 4-year-old daughter was released to her mother.
