Oscar De La Hoya is being accused of sexually assaulting a woman on two occasions ... with the former co-worker alleging the boxing star brutalized her, causing "severe physical and emotional damage" that plagues her to this day.
But, the boxing Hall of Famer is adamantly denying the claims ... accusing the woman of being nothing more than a bitter employee who was fired.
“Unfortunately, with twenty-four-hour news cycle, we find ourselves today, more often than not, as the recipient of vindictive and unjust accusations that are interpreted and spread as truth -- without any evidence to support erroneous claims," Oscar's rep told TMZ Sports in a statement.
