Dallas Mavericks owner Mark Cuban has denied allegations of a 2011 sexual assault after a Portland, Oregon newspaper published details of the case in wake of a Sports Illustrated report that labeled the Mavericks workplace, "a corporate culture rife with misogyny and predatory sexual behavior."

According to a police report obtained by Willamette Week's Nigel Jaquiss, Cuban was accused of sexually assaulting a women at a Portland bar after she asked him for a picture. 

"He then moved his hand down until it was on her buttocks," Portland Police Detective Brendan McGuire wrote in his summary of the woman's statement. "Cuban then pushed his hand down the back of her jeans and inside her underwear where he cupped his hand over her groin area and inserted the tip of his finger into her vagina."

The woman also reportedly provided Portland Police with seven photos, two of which Detective McGuire deemed "significant." However, the Multnomah County District Attorney's never pressed charges, citing insufficient evidence.

"In both images, Cuban's right shoulder is lowered and he appears to be stretching to reach his arm down," the detective's report says. "In one of the pictures, his arm can be seen behind [the alleged victim] and it appears Cuban is reaching down toward her buttocks."

Cuban denied the allegations in an email to the paper, saying, "It didn't happen." He also relayed a memo to the Dallas Morning News confirming prosecutors opted not to file charges.

"The case detective and the complainant both agree with the conclusion there is no corroborative evidence to support the complaint's allegation. The complainant has also consistently and repeatedly stated to police investigators she does not want to pursue this matter further. The complainant requested documentation and investigation of her complaint but has confirmed with me she will not participate in a criminal prosecution and agrees her claim cannot be proven."
