TORONTO

The trial of two Toronto doctors accused of drugging and gang sexual assault began Monday with a Crown attorney describing some of the alleged attack.

Cara Sweeny told court the alleged Feb. 12, 2011, incident began when a 23-year-old woman met with the men at a downtown Toronto hotel for career advice. They shared drinks and ended up at another bar, where the woman lost vision and then blacked out.

Sweeny alleged the doctors, Amitabh Chauhan and Suganthan Kayilasanathan, drugged the woman and took her to a hotel room where she was sexually assaulted.

Sweeny said the woman will testify that she remembers only shreds of the alleged attack. However, she does recall one man standing in front of her and the other behind her, both taking her clothes off and talking to her, she said.

“They said she was a ‘dirty girl’ and ‘don’t you like this?’” Sweeny told the court.

Sweeny said the woman visited two hospitals for pain related to the attack after she left the hotel. A rape kit was administered at the second hospital.

The Crown also said DNA tests showed the men’s bodily fluids were found on the woman’s genitals, underwear and bra.

A 29-year-old woman, who cannot be identified because of a publication ban, testified Monday that she had a date with Kayilasanathan in 2008 which bore some similarities to the other woman’s experience.

She said that after going to a bar with the doctor she blacked out, waking up in his bed the next morning. She doesn’t know if she was sexually assaulted, but felt so weak she couldn’t get up. She felt “nailed to the bed,” she told the court.

“I’ve been hungover before,” she said. “That was no hangover.”

But Kayilasanathan’s lawyer, David Humphrey, questioned the reliability of the woman’s memory, focusing on how many drinks she had that evening. He pointed out that when she initially contacted police she thought her date with the doctor was in 2009, a year after it actually occurred.

The woman is a "similar fact" witness. Neither doctor has not been charged with any crime in relation to the woman.

Canadian-born Chauhan and Sri Lankan-born Kayilasanathan are charged with administering a noxious substance and gang sexual assault.

The trial continues Tuesday.
