A 17-year-old youth pleaded not guilty to an armed robbery charge after he allegedly stole two cellphones at knifepoint in Dorchester, Suffolk prosecutors said.
Boston police arrested the youth Wednesday night. He is not being named because he is a juvenile, police said.
The two victims, a man and a woman, reported the alleged crime just before 7 p.m. Wednesday. The pair told police that three men had approached them as they were walking behind the Richard J. Murphy School on Worrell Street.
The female victim said one of the suspects grabbed her and demanded the pair’s cellphones while the other two suspects assaulted her friend, knocking him to the ground, police said. During the struggle, one of the suspects allegedly pulled out a knife and cut the male victim on his hand.
The three suspects were able to steal the victims’ cellphones before fleeing on foot toward Victory Road.
An off-duty police officer in the area recognized two of the suspects from their description when he saw them running behind an apartment building on Neponset Avenue.
One of the suspects, the 17-year-old, was arrested after police detained him and found a black folding knife in his possession. The second person was released.
The third suspect was not located and the victims’ cellphones were not recovered, police said.
At the youth’s arraignment in Dorchester District Court Thursday, he was held on $2,500 cash bail, said Renee Nadeau Algarin, a spokeswoman for the Suffolk district attorney’s office.
He is to return to court June 10, according to Algarin.Catalina Gaitan can be reached at email@example.com. Follow her on Twitter at @catalina_gaitan.
