Robber beaten up by 82-year-old grandmother

A man in the US got more than he bargained for in a robbery when the 82-year-old grandmother he believed to be frail, pummeled him to the ground.

On Thursday night Willie Murphy was in the middle of her bedtime routine in Rochester New York when she heard the man bang on the door. 

Murphy told WHAM-TV she called the police and refused to let him in but the man broke the door.

"It's kind of semi-dark and I'm alone, and I'm old. But guess what, I'm tough.

"He picked the wrong house to break into," she told WHAM-TV, flexing her muscles.

Unfortunately for the intruder, Murphy is a competitive powerlifter and was named the World National Powerlifting Federation (WNPF) Lifter of the Year in 2014 in her age bracket.

When the intruder entered her home, she told WHAM-TV grabbed a table and began to hit the man.

"I took that table and I went to work on him, and guess what, the table broke. 

"And when he's down I'm jumping on him."

When the man was on the ground Murphy ran to the kitchen, grabbed a bottle of baby shampoo and emptied it onto the man's face.

"I grabbed the shampoo. He's still on the ground. In his face, all of it, the whole thing."

She then grabbed a broom and began hitting him.
