The stabbings happened on the pier at around 8:30 p.m. Wednesday. The victims were taken to area hospitals with non-life threatening injuries.
This started as a dispute between the three victims and two other men. It's not clear what the argument was about.
The victims were stabbed and the suspects took off, but police managed to arrest both of them in the vicinity of the pier. Charges are pending.
A knife was recovered at the scene.
Pier 84 is located off 12th Avenue at West 44th Street. It is just south of the Intrepid.
