Three Canadian women were arrested for attacking a fellow partygoer at the swanky W Hotel in Times Square on Sunday.

Port Authority police say the assailants attacked their 35-year-old victim with a champagne bottle and drinking glasses during a party at the hotel. An ambulance took the woman to Bellevue Hospital, where she was given 36 stitches.

The attackers, identified as Monique Boakye-Yiadom, 35; Aleesha O. Williams, 26; and Amy C. Walker, 30; were arrested after the victim reported the assault to a Port Authority officer stationed at the Lincoln Tunnel. The women were driving a black Chrysler with Ontario plates, which he found nearby.

All three were charged with gang assault, first degree assault and criminal possession of a weapon.
