THE BRONX - Police have released surveillance video of a man who they say robbed a woman inside her Fordham apartment building after she held open the door to let him inside.

The video shows the suspect following his victim up the stairs before pulling out a gun and demanding her purse. He was seen rifling through the woman's possessions even before leaving the building.

Police say it happened about three weeks ago in broad daylight.

The man is described as being Hispanic and about 25 years old.
