Video posted on YouTube shows a young man brutally attacking an elderly man as witnesses laughed.
The video was shot with a cell phone and shows the beating at the public housing complex on Wade Park. CMHA police used video of the vicious attack to arrest Simmie Barker, III.
Charles Langford was attacked for helping a neighbor who was reportedly being harassed by Barker and a friend.
"(Simmie) wanted to come in here and claim he had $600 in my home, and he didn't," the woman told 19 Action News. "Charles just came to defend me, and make sure my house was all right."
Investigators charged Barker with felony assault and burglary.
