One teen has been charged with murder and three others have been arrested in the June stabbing death of a 17-year-old in Brooklyn, the NYPD says.

Police responded to a call of a person stabbed at the corner of Benson and 26th avenues in Gravesend June 9, and discovered Kenny Chen with stab wounds to his torso. Chen, who was unconscious, was transported to Coney Island Hospital where he was pronounced dead.

On Tuesday, police arrested the four 17-year-old suspects. One is charged with second-degree murder and two counts of gang assault. The other three suspects were all charged with gang assault.
