Three teenagers were arrested and charged on Wednesday after D.C. police say they carjacked a victim at gunpoint and attempted to rob businesses while armed earlier this month.

A series of crimes were carried out by the teenage boys — aged 14, 15 and 16 — over a period of about a week, according to D.C. police.

The crimes started with an armed carjacking which happened on Wednesday, Feb. 14, at around 2:45 p.m. in the 800 block of 46th Street in Northeast. Police said the 15- and 16-year-olds pulled out handguns on a driver sitting in his car and stole his vehicle.

On Tuesday, Feb. 20, all three teens allegedly went inside a store in the 4600 block of Sheriff Road Northeast shortly before 8:30 p.m. Police said one of the boys pulled out a handgun and the group demanded money, but left the store without taking anything.

Later that morning, just before 11:40 a.m., the 14- and 15-year-old are accused of going inside a store in the 4800 block of Nannie Helen Burroughs Avenue in Northeast. As with the earlier attempted robbery, the teens left with nothing, despite one of them pulling out a handgun, police said.

Police said the 14-year-old was charged in the Sheriff Road and Nannie Helen Burroughs Avenue attempted armed robberies, the 16-year-old was charged in the 46th Street armed carjacking, and the 15-year-old was charged in all the crimes, including a charge of possession of an unregistered firearm and possession of a large capacity ammunition feeding device.

Separately, the 16-year-old was also charged in an armed robbery that happened on Jan. 28 in the 1000 block of 45th Street in Northeast, police said.
