Two Indian doctors have been arrested and charged with gang sexual assault of a 23-year-old woman in downtown Toronto

Amitabh Chauhan, 32, and Suganthan Kayilasanathan, 32, were arrested, made brief court appearances and were ordered held in custody. Police say the victim knew one of the doctors and met him in the bar of a hotel. "She went to the bar under the pretense of being given career advice," said Const. Tony Vella, spokesman for Toronto police. "Unbeknownst to her a second man appeared and they both sat down ..." Investigators say the three then moved off to another bar. They believe that's where the woman was given an unknown substance that made her lapse in and out of consciousness. "She was taken back to the original hotel and she was taken up to a room where she was allegedly sexually assaulted by the two men," said Vella. Chauhan and Kayilasanathan are both active medical doctors in the area. Both men have been charged with administering a noxious substance and gang sexual assault. Vella said investigators believe there may be other victims.
