A older teen was stabbed several times while riding the 14 Mission this week. "The 18-year-old victim was riding an outbound 14-Mission bus when he got into a fight with a 19-year-old man at about 1:40 p.m. Wednesday," reports BCN (via SF Appeal). "The pair continued arguing until the bus neared Mission Street and Foote Avenue, where the 19-year-old stabbed the victim."

The victim remains in critical condition.
