A Washington man who allegedly robbed a house at Ninth and N streets NW yesterday morning was seriously injured soon after when the robbery victim spotted him walking along a street a short distance away and ran over him with a Lincoln Continental, police said.

The injured man, Napoleon Walker, 27, of 1446 Belmont St. NW, was taken to the Washington Hospital Center where he was listed in stable condition and later charged with armed robbery.

Police said that about 9:30 a.m., Walker, who identified himself as a student at Howard University, entered a house at 916 N St. NW where several persons had gathered.

Walker pulled out a gun and told one of the persons, truck driver Alfred Perry of Washington, to go into a bathroom. Walker followed Perry into the bathroom and took his money and jewelry, police said.

Perry told police that afterward, he drove around looking for his assailant and spotted Walker in the l000 block of N Street NW. Perry said when Walker saw him, Walker aimed a gun at the car. Perry said he ducked, pressed the car's accelerator to the floor and ran over Walker.

Police said the car then slammed into the stairwell of a town house at l008 N St. NW, severely damaging the vehicle. Perry was not injured in the crash.
