A woman who accused Conor McGregor of sexually assaulting her after a 2023 NBA Finals game has filed a lawsuit against the former UFC star.

The lawsuit filed Tuesday also alleges gross negligence on the part of staff and security at the CaSea Center, home of the Miami Heat.

The woman, a 49-year-old Miami-Dade County resident who worked as a vice president at a "prominent financial institution" on Wall Street, claimed McGregor sexually assaulted her in a bathroom, according to the lawsuit. On June 9, 2023, the court after Game 4 of the NBA Finals series between the Heat and the Denver Nuggets.

The civil lawsuit stems from the same criminal sexual assault charge filed against McGregor in June 2023. An incident report was filed with the City of Miami Police Department on June 11, 2023, at 6 p.m., less than 48 hours after the alleged sexual assault. The Florida Attorney's Office declined to file charges in the alleged attack that occurred in October 2023.

"After a thorough investigation at the time, the state attorney concluded that no case needed to be pursued," McGregor's attorney, Barbara Lines, said in an emailed statement to ESPN. "Nearly two years later, the state attorney concluded that no case needed to be pursued. At least three attorneys later, the plaintiffs have a new false story and we are confident this case will be dismissed as well."

A Heat spokesperson told ESPN in an email that the organization would not comment on the lawsuit.

McGregor, 36, also denied the accusations in 2023, with Llanes telling ESPN at the time that the former UFC lightweight and featherweight champion "will not be intimidated."

The lawsuit seeks medical bills, damages and other relief deemed reasonable by the Heat and McGregor.

The woman's attorney, Jim Dunn, wrote in an email to ESPN that his client is filing the civil lawsuit to "raise awareness and encourage others to report sexual assault."

"My client thought long and hard about her decision to file this civil case and was concerned about the impact it might have on her job on Wall Street," Dunn said. "Nonetheless, her primary goal in filing the lawsuit was Raise awareness and encourage others to report sexual assault.”

The complaint, filed Tuesday in the U.S. District Court for the Southern District of Florida, accuses McGregor of "knowingly engaging in unlawful sexual contact" without the woman's "consent or permission."

After the Nuggets' game against the Heat, the lawsuit alleges McGregor and the woman began talking in the courtside clubhouse inside the Kasea Center. An acquaintance of the woman said that as she and the woman were leaving, a member of McGregor's team allegedly told the woman "Conor told me to come pick you up," before grabbing the woman's wrist. The woman claims she asked to be released but was told: "No, if I lose you Connor will kill me."

McGregor grabbed the woman's hand or wrist in front of the men's restroom and led her into the restroom while her acquaintance followed her, the lawsuit said. The woman was then allegedly taken to a booth, and the lawsuit alleges security and/or staff at Kasea Center did not allow the acquaintance to follow. McGregor then attacked the woman in the booth, the lawsuit states.

Dunn told ESPN in a separate phone interview that his client filed the civil lawsuit because it was "her only way to seek justice" after Miami-Dade County decided not to pursue criminal charges. The statute of limitations for civil cases involving alleged gross negligence is two years.

The lawsuit also references an incident earlier that night in which McGregor punched Heat mascot "Bernie" twice during an on-court skit promoting pain relief spray, sending the man to the hospital . The lawsuit alleges that the mascot's injuries were known to arena staff but were not known to the public during the games.

Dunne claims McGregor received special treatment from arena staff because he was allowed to stay in the arena and was still offered alcohol after the incident with Burney, which took place before he allegedly assaulted the woman . As a result, the suit alleges, Kasea Center staff "knew of the heightened risk that McGregor would commit assault."

McGregor last competed in the UFC in July 2021, when he lost via TKO to Dustin Poirier at UFC 264 in Las Vegas.
