Police arrested four teens Tuesday night in the June murder of Kenny Chen, the 17-year-old who was stabbed steps outside his Bensonhurst home.
Peter Sedeno, 17, of Woodside, was charged with murder and gang assault. The other 17-year-old suspects -- Daquan Jackson of Middletown, N.Y.; Dayshawn Young of Gravesend; and Daine Daley of St. Albans -- were charged with gang assault.
Chen was found with a stab wound to his torso on the corner of Benson and 26th avenues around 3:45 a.m. on June 9. He was taken to Coney Island Hospital, where he was pronounced dead.
An NYPD spokesman said the suspects had an altercation with Chen earlier in the day. He said the killing may be drug related.
