The incidents occurred aboard MUNI. Six suspects (described as 5-6 black male juveniles) got aboard the bus at Masonic and Oak Streets. One of the guys (black male 13-16 years, 5'6", with short blond twisties, wearing a white t-shirt, khaki pants, with a diamond stud in his right ear) was acting crazy and once on the bus let his pants drop to his ankles and attempted to sit on a woman's lap. When a man (53-year-old victim) attempted to intervene, the suspect and friends knocked him to the ground and hit him several times before jumping off the bus. The victim received minor injuries, the suspects were not located.
