At least six people were injured, including five teenagers, when gunfire broke out at a barbecue in the Bronx.
The shooting happened just after midnight at Concourse Village.
Police say it was sparked by some sort of fight, but the exact circumstances are still unclear.
Investigators have not said whether they are looking for more than one shooter.
The victims range in age from 14 to 20. Five are males, while one is a 19-year old female. All are expected to make a full recovery.
Police are interviewing the victims to try to determine what led to the shooting.
