Philadelphia police say they have arrested a 15-year old for a “Knockout” attack and are currently looking for a second suspect.

According to CBS Philly, the 15-year old was arrested “in connection with a ‘Knockout’ attack in Northeast Philadelphia earlier this month.” The victim was Mark Cumberland.  

Cumberland said he walked out of a pizza place and was asked for a cigarette. While he was digging in his pockets for a cigarette, four teens began hitting him. He is still having trouble seeing, as well as “breathing and swallowing,” as a result of the attack. 

The 15-year old “was charged with Aggravated Assault, Criminal Conspiracy, and related charges” in the attack on Cumberland. 

Police in Lower Merion Township, PA arrested two suspects for a similar “Knockout” attack on a 60-year-old man who was walking his dog in late October.
