A Vietnam veteran was so badly beaten up in a random attack by a gang of teenagers that his skull was fractured.
Edward Schaefer, 64, who lost an eye while serving his country, was attacked from behind as he walked to meet his wife at a bus stop in the Olney district of Philadelphia.
Police have now arrested one of the six male suspects, after dozens of tip-offs from the public and help from schools, CBS News reported.
But the search is on for the remaining members of the gang who left Mr Schaefer with injuries to his head and hands.
Officers say one of the gang started the attack and then the others joined in.
The attack would of been a lot worse had it not been for the intervention of a good Samaritan who scared off the thugs, say police.
Donald Jones told CBS: ‘He fell and that’s when I came across the street. When they saw me, that’s when they scattered.’
‘He was trying to talk and I said: “No, stay there. I got you.”‘
Immediately after the attack the teenagers fled on foot.
Kate Schaefer, the victim’s wife, told Eyewitness News, ‘They just smashed every bone in his face. I can’t tell you the words. I guess I was just happy that he was alive.’
The attack happened shortly after 6pm on Tuesday.
Lt. George McClay said.’These animals are specializing on our elderly people out here and a gentleman who served our country.’
He added: ‘I’m disgusted by this whole thing. I’m surprised he survived.’ Lt McClay said ‘one more shot the wrong way’ and Mr Schaefer could have died.
The suspects who are described as six black and Hispanic males, between the ages of 16 to 18.
Police are offering a $1,000 reward for information leading to their conviction.
