TORONTO - A Toronto man accused of sexually assaulting a fellow York University graduate student has been found guilty.

Mustafa Ururyar was convicted of forcing Mandi Gray, a PhD student with whom he was having a casual relationship, to perform oral sex and engage in sexual intercourse in the early hours of Jan. 31, 2015.

Ururyar was accused of assaulting Gray in his bedroom after a night of drinking with friends at a pair of bars in downtown Toronto.

Gray testified that Ururyar had been verbally abusive to her that night, causing her to feel uncomfortable being in his company.

Ururyar pleaded not guilty, testifying that he and Gray had engaged in consensual sex that night.

He testified that Gray had been sexually aggressive the entire night, groping him at the bars and initiating sex even after Ururyar tried to break up with her once they got home.
