A woman and her two children were robbed in the stairwell of their Laurel apartment building Saturday night, Anne Arundel County police said.

The woman was climbing the stairs of her building in the 100 block of Lauren Dr. with her children at 9:40 p.m. when a masked man with a gun came up from behind and demanded she turn over her purse, police said.

The woman gave the man her purse and he ran off. Police could not find the man, who was described only as a black man wearing a face mask, light gray sweatshirt and a black backpack.

The woman and her children were not injured, police said.
