PHILADELPHIA (CBS) - Philadelphia police say they have arrested two suspects who were caught on tape randomly attacking an elderly man who was walking down the street Wednesday afternoon.

Northwest Detective Sgt. Andrew Kensey says the 65-year-old Asian man was walking along the 400 block of Chelten Avenue in Germantown at about 3 p.m. when one of the teens snuck up behind him and struck the man in the head.

The teens then ran away from the scene and did not take anything from the victim.

“He has a severe head injury, brain bleed as a result. He’s lost several teeth. He’s lost some blood. His jaw has been wired shut,” Kensey explained.

“This is a random, heinous act of violence on an innocent elderly male, who is walking down the street minding his business. This should not have happened,” Kensey explained.

The victim remains hospitalized in stable condition at Albert Einstein Medical Center.

The suspects turned themselves into police early Thursday morning. Police say they are a 16-year-old and a 19-years-old named Samuel Cave of the 400 block of Champlost Street. Investigators say they believe Cave is the one who struck the victim.

Sources say the mother of one of the suspects recognized her son on television and had her son turn himself into police. The second suspect later followed suit.

“I was upset with the guys that hit the elderly man,” said Cave’s mother Carol. “I was saying, ‘They should go to prison.’”

Sources also say the suspects reportedly admitted to their roles in the crime. They will be charged with Aggravated Assault, robbery and related offenses.
