Film shows attack on 101-year-old

For a moment, the man in the grainy video looks like a good Samaritan holding the door open for an elderly neighbor. Then he turns and delivers three sharp punches to the 101-year-old woman’s head.

“The next thing I knew, I had a big bang on the side of my face,” said Rose Morat, who suffered a fractured cheekbone and lost her purse and $33 to the mugger.

The attack was captured by a surveillance camera in the lobby of her Queens apartment building last week, and police are searching for a suspect.

“I’m quite sure that if it had happened when I was younger, I would have been after him,” Morat said.
