OVERBROOK FARMS (WPVI) --Philadelphia police have released surveillance video as they work to track down the teen they say punched a man in the face as he walked his dog.
It happened around 1 a.m. May 21 on the 1100 block of North 66th Street in Overbrook Farms.
In the video, a group of kids is seen trying to get into nearby parked cars.
Police say one of the kids, believed to be a teenage boy, walked up to a 61-year-old man and asked a question.
"Walks up to the gentleman and asks him for the time; male looks at his phone, gives him the time. As he's doing that, the young man just cold-cocks him in the jaw, knocking him to the ground," said Philadelphia Police Lt. John Walker. "Fortunately he fell on his side so he didn't hit his head."
The video shows the teen jump on top of the man, and take his cell phone.
The victim was treated at Penn Presbyterian Medical Center for a broken nose and concussion.
"You see the poor dog trying to help his owner, but the dog is so small that he's trying to bit the kid's ankles, but he's so small he's unable to," said Walker.
In the video, the suspect can be seen wearing shorts with a light colored hoody and a backpack.
Police say they think the teen lives nearby.
"So we are asking the neighbors in that community to clearly identify these kids. They can call the tip line anonymously (at) 215-686-TIPS," said Walker.
Anyone with information is asked to contact police.
