Dramatic video captures armed home-invasion suspect disguised as a mailman

The victim was zip-tied, duct-taped and pistol-whipped inside his home.

— -- Dramatic surveillance video captured the moment police say a home-invasion suspect disguised as a mailman pulled out a gun, forcing a man into his Philadelphia home in broad daylight.

The suspect was seen suddenly pulling out a gun and forcing the victim into his home, police said.

Moments later three more suspects run into the house, where police say they zip-tied, duct-taped and pistol-whipped the victim.

No shots were fired, police said. The victim suffered minor injuries and the infant wasn't harmed, police said.

Two suspects fled in a newer black Buick Lucerne while the other two fled in a gray Pontiac sedan, police said. Video surveillance captured both cars circling the block about an hour before the home invasion happened, police said.

The suspects remain at-large. Anyone with information is asked to contact the police at (215) 686-3353.
