KINGSTON, Ont. — Another sexual assault case at Kingston's Royal Military College is under investigation, National Defence officials have confirmed.

The alleged attack happened on May 13 — a day before the college's annual convocation.

Capt. Joanna Labonte said military police continue to investigate the allegations and charges have yet to be laid.

Earlier this month, two cadets faced a court martial with sexual assault charges.

Officer Cadet J.C. Scott was found guilty of a lesser charge. He was fined and received a severe reprimand.

The other, Officer Cadet A.R. Whitehead, 22, is currently facing court martial.

The charges come at at a time Canada's military is under the microscope for having a “sexualized” culture that is hostile to women.

According to a recently released independent report ordered by the chief of defence staff, the military is awash with a range of sexual misbehaviour, including "highly degrading expressions that reference women's bodies, sexual jokes, innuendos, discriminatory comments with respect to the abilities of women and unwelcome sexual touching."

It also found cases of sexual harassment and sexual assault, including date rape.

"At the most serious extreme, these reports of sexual violence highlighted the use of sex to enforce power relationships and to punish and ostracize a member of a unit," the report said.

Sexual harassment and sexual assault cases were not frequently reported to military officials, the review also found.

At Whitehead's court martial Wednesday, a recent graduate of the college testified Whitehead raped her in her dormitory room in the fall of 2013 and several months later told her that "he would try to keep his hormones in check."

The victim a 22-year-old who is now a second lieutenant, is the second of two former classmates to accuse Whitehead.

Both women have received their commissions, while Whitehead hasn't been permitted to graduate and is on trial in military court on two charges of sexual assault.

The second complainant told military Judge Col. L.V. d'Auteuil that Whitehead was a friend at the time and had dated one of her friends.

The night of the alleged assault, she testified, was around Halloween. "We'd just finished the first wave of midterms," she recalled, and a group of them, including Whitehead, went downtown to Fluid nightclub around 11:30 p.m.

She said she returned to her dormitory by cab -- after an extended stopover at McDonald's fellow cadets -- and went directly to her room.

"I was really drunk and I was really tired and I just wanted to go to bed," she testified, adding she estimated she'd been asleep about 10 or 15 minutes when she was awakened by knocking at her door.

She told d'Auteuil it was Whitehead, and she let him in and went back to bed, unconcerned "because I'd known him by then about two years and I'd never known him to be anything but a decent guy."

On that night, however, she said, Whitehead sat down near her head and tried to kiss her.

She said she "jerked back," intending to back up against the wall, but ended up banging her head against it. Whitehead tried to undress her and ended up on top of her, she testified.

"He took my dress off," she told the judge. "I know that I tried to stop him, but I don't think I was successful at the time."

She said Whitehead then undressed and "he started sleeping with me."

Prosecutor Maj. Maureen Pecknold asked the second lieutenant about her condition when she woke up.

"If you're asking me if I was aware or not that I had intercourse, the answer is 'yes.' I was aware."

Whitehead's other accuser testified earlier in the trial that she was the one who initially spoke to the female padre, after Whitehead made advances toward her in early September 2013 also following a night of drinking in Kingston's downtown.

She said she rejected him but was troubled that he'd later followed her into the women's showers, which are off limits to men.
