ST. LOUIS — Police are looking for a man seen in security video attacking and robbing a 79-year-old man in the man's own home Friday afternoon.

Police said the victim was in his own home when he saw a man on his front porch. The man forced his way into the home on Lafayette at around 1 p.m. and pulled out a gun.

The video shows the man hitting the victim in the head with the gun before forcing him to the ground. Police said he stole the victim's cell phone and other property before running off.

The victim was taken to the hospital for treatment. 

A neighbor and friend, Frank Gilsinn, says the victim was just treated for bumps and bruises and is staying with loved ones for a few days while he heals.

In the meantime, he says he will be changing his own routines.

"If you come up to the door, I’m not going to open up the door for you, I’m going to talk through the door," says Gilsinn.

Anyone with information in this case is asked to call 866-371-8477.
