There are hundreds of robberies in the District, and victims give many descriptions of the robbers. But a description given to police Friday seemed to stand out: It was of a child less than 5 feet tall and no more than 10 years old.

The description was given in connection with an armed robbery on Madison Street NW, between Third and Fifth streets in the Brightwood-Manor Park area, D.C. police said. The holdup was carried out in mid-afternoon by two youngsters on bicycles.

One of the two robbers was described to police as 4 feet 6 to 4 feet 8 inches tall, police said. He was also described as black, slim, with a light complexion and twists in his hair. He was wearing a red T-shirt, and police were told that he appeared to be 10 years old.

The other robber was described as black, 13 to 14 years old, about 5 feet 3 to 5 feet 5 inches tall and slender. He had a medium complexion and wore a black tank top and black shorts. He had a high-top haircut, police were told.

According to police, the two youngsters, on bicycles, approached the victim about 2:30 p.m. One had what was described to police as a handgun. The robbers demanded the victim’s property, police said, but it was not clear whether anything was taken.

Police said the victim was also a boy.

The incident comes as the District has seen a recent spike in violence. There have been 97 homicides this year, up about 30 percent from this time last year and almost reaching last year’s total of 105.
