Police are looking for a young man who punched an unarmed 58-year-old man sitting at a suburban Philadelphia trolley stop in a videotaped attack posted on social media.
Upper Darby police Superintendent Michael Chitwood told the Philadelphia Daily News the assault was unprovoked, calling it an incident of the “knockout game” and a “violent, vicious, cowardly, punk act.”
The video of last week’s attack at the Aronimink station was posted by one of the four boys involved, police said. In it, one of the boys approaches the man and, after a brief exchange, punches him in the jaw as the others laugh.
Chitwood, who said police have received many tips about the identity of the assailant, vowed to “take him out in cuffs.”
