PARK SLOPE, Brooklyn -- Three people were injured and a fourth is in custody after an incident outside a Brooklyn high school Wednesday.

Authorities say two people were slashed and another bitten in front of 237 Seventh Avenue in Park Slope, after the John Jay High School graduation.

A 19-year-old man was wounded on the back and hand, while a 42-year-old man was slashed in the left ear. The third victim, a 17-year-old, was reportedly bitten in the chest.

All three were taken to Methodist Hospital in stable condition.

Police have a 20-year-old male in custody. They say he was not a student and was apparently attending the graduation.

The circumstances of the incident are not known at this time.
