SYRACUSE, N.Y. (WHCU) — There’s been another arrest after a large gathering in Syracuse nearly a month ago left more than a dozen people injured.

Police say the 17-year-old helped coordinate an attack on a 19-year-old girl at the gathering, who suffered a laceration on her head. The suspect was charged Wednesday with gang assault, second degree assault, and criminal possession of a weapon.

It’s the fourth arrest since the June 28th party on Massena Street.
