The video of the assault against Smith depicts four youths. According to police, it happened around 3 p.m. May 29 on Chelten Avenue near Knox Street. The boys engaged Smith, who works as a customer service attendant at the Cheltenham ShopRite, in conversation when "for no apparent reason" one of the youths, a 12-year-old boy, punched Smith in his face when he was not looking, police said in a news release. A 15-year-old punched him a second time, and a 13-year-old laughed at the assault in the video, which was recorded by a fifth youth, a 15-year-old, police said. A police spokeswoman said she did not know the status of the fourth youth.
