Two teenagers and a young adult were stabbed Monday evening outside a Southeast Washington recreation center when police said they tried to rob four people of a designer Helly Hansen jacket, sneakers and headphones, according to authorities.

D.C. police charged two of the three people who suffered wounds; the third escaped. The two youths who police said were targets of the robbery, including a 17-year-old who wielded the knife, were not charged.

The incident occurred about 6:30 p.m. outside the Benning Stoddert Recreation Center just south of East Capitol Street, near the River Terrace and Greenway neighborhoods.

Officer Araz Alali, a D.C. police spokesman, said five people — including two 15-year-olds and a man — approached four people from behind and demanded that they turn over the jacket and other apparel. Alali said the assailants surrounded the group and hit several, including a 17-year-old wearing the Helly Hansen jacket.

Alali said the 17-year-old took out a pocket knife and swung it at the five attackers, striking two 15-year-olds and the adult male. That wounded adult and two others escaped. Alali said the two teens were taken to an area hospital with wounds that are not believed to be life-threatening. Alali said they were each charged as juveniles with assault with intent to rob. Their names were not released because of their ages.

An earlier version of this story, based on police accounts, gave a different number of alleged attackers and victims. A final police report clarifies the numbers.

The Helly Hansen jacket was sought after in 2012, with several robberies and at least one fatal shooting attributed to the clothing line. In December, six teens were sentenced to up to 30 years in prison in the 2012 killing of Olijawon Griffin, 18, who had confronted them at the Woodley Park Metro station after his Helly Hansen jacket was stolen.
