Nassau police are looking for four people they say robbed a young Baldwin couple at gunpoint in their home.

First Squad detectives said on Wednesday at 1 p.m. a man knocked on the door of the Brooklyn Avenue home. When the 19-year-old man who lived there answered, the man flashed a gun, entered the home and ordered him and the 18-year-old woman who lived there to lie on the kitchen floor.

Three other robbers then came in, taking cellphones, money, jewelry and an Xbox video game system from a bedroom before leaving.

Police don't know if the robbers had a vehicle.
