Mark Cuban was investigated for sexually assaulting woman in 2011

Cuban also denied the allegations in an email to the paper.

According to the report, the woman told investigators that Cuban reached into her trousers and inserted a finger into her vagina while they were taking a picture in the nightclub.

Explaining their decision in a report, prosecutors wrote that "there is no evidence to corroborate the complainant's statement and there is evidence contradicting the claim", and that the woman chose not to proceed with her claim.

"These allegations are thoroughly investigated by the Multnomah County District's Attorney's Office and the Portland Police Bureau", Cuban's attorney Stephen Houze said in a statement.

"She said she was anxious about the potential publicity and did not want to be labeled as "that girl" involved in a sex scandal with Mark Cuban", the redacted report reads. He also voluntarily passed a polygraph test, according to the report.

She reportedly told police two weeks later, including in her complaint seven photographs taken of her and Cuban.

According to weekly publication, a police transcript detailed the woman's claim that she asked Cuban for a photo op in Portland's Barrel Room. "I stand behind that report 1,000 percent". One image is described as "Cuban reaching down towards her buttocks".

After initially being embarrassed about what she says happened, the woman went to the police a week later. But McGuire did say, "There are two pictures that do appear to have your shoulder dipping and your arm sort of, if you follow the direction of it, down below her waist".

McGuire also noted the alleged victim's expression: "Her teeth are clenched, eyes wider than the other pictures and brow raised showing a look of surprise and strain". The woman, who was not identified in the article, told Willamette Week, "I really left it in the past".
