UFC star Conor McGregor faces serious allegations after attending Game 4 of the NBA Finals between the Denver Nuggets and Miami Heat.

The Irishman was accused of raping a woman after the game held at the Kaseya Center in Miami.

McGregor's representatives released a statement on Thursday morning, denying the allegations.

"Mr. McGregor will not be intimidated," they added.

The 34-year-old allegedly sexually assaulted a woman "violently" inside a men's bathroom, according to TMZ Sports. The incident occurred right after the Nuggets won 108-95.

The demand letters, which the accuser's attorney Ariel Mitchell authored, added that the UFC star shoved his tongue in the victim's mouth and aggressively kissed her after the NBA game. It also claimed that Miami Heat security separated the woman from her friend and forced her into the bathroom.

McGregor also forced the woman to have oral sex with him and attempted to sodomize her.

Mitchell also stated that the woman was able to elbow McGregor repeatedly, giving her a chance to escape. Being in a hurry, she left her purse in the bathroom. McGregor's security guards "held hostage" the purse until she pleaded with them for its return.
