Graphic allegations have emerged in the case of three Toronto police officers accused of sexually assaulting a female parking enforcement officer while she was too drunk to consent or stay conscious.

After an application by Postmedia News, CTV, and the Toronto Star, a Superior Court justice lifted a publication ban on the statements used to secure a search warrant in the case.

While the three officers from the Toronto Police Service's downtown 51 Division — Leslie Nyznik, Sameer Kara, and Joshua Cabero — were charged with sexual assault and gang sexual assault last year, the court documents unsealed this week reveal the shocking nature of the specific claims against them.

According to the female officer's account of the night, Kara invited her to a police "rookie night" party on Jan. 16, 2015. She said that Kara told her a hotel room had been rented for the night to avoid anyone drinking and driving.

After a night of drinking, the four ended up at a room at the Westin Harbour Castle hotel, where the complainant was allegedly assaulted.

She told investigators she was too drunk to move, and had been slipping in and out of consciousness.

The female officer said she remembered Nyznik holding her head up and inserting his penis into her mouth. She also recalled being penetrated vaginally several times in the night, she said.

'Unable to form the words'

She said she did not tell Nyznik and Cabero to stop because she was "unable to form the words," according to the National Post.

The woman told a friend she would never agree to group sex, but was hesitant to report on fellow police officers, according to the Toronto Sun.

The woman went to the hospital the next day, where a sexual assault nurse performed a rape kit on her and found signs of anal penetration, reported The Toronto Star.

A few days later, she threw up at work and told a supervisor she had been sexually assaulted.

The allegations have not been proven in court.

Police used these documents, which included summaries of the woman's interview with police, to obtain warrants for DNA from the accused, because they refused to provide voluntary samples, according to The Star.

Nyznik, Kara, and Cabero were charged in February 2015 and suspended with pay. Released on $15,000 bail, all three plan to plead not guilty, according to their lawyers.
