A patron observed 2 suspects playing 3 Card Monte while on board a Daly City train. The patron off-boarded at the Balboa Park station and the two suspects followed him. The two suspects then punched the victim and attempted to take his I-phone and I-pod. The victim was able to maintain his property and the suspects fled in an unknown direction. The victim called BART police the next day, to file a report. The first suspect was described as a black male in his early 30's, 6' tall, wearing a baseball cap with a red bill, red striped shirt, and dark pants. The second suspect was described as a black male, 6' 2" tall with a goatee, wearing a white T-shirt, and black pants.
