Mixed Martial Arts: Conor McGregor denies sexual assault allegations after being arrested in Corsica

Mixed martial arts star Conor McGregor has "vigorously denies any accusation of bad behaviour" after he was arrested and accused of sexual assault while on a trip on the French island of Corsica.

Prosecutors on the Mediterranean island confirmed that the Irishman was arrested on Friday (NZ time) and McGregor's representatives have since told ESPN he was released without charge. 

In a statement to the Agence France-Presse, local prosecutors said: "Following a complaint filed on September 10 denouncing acts that could be described as attempted sexual assault and sexual exhibition, Mr Conor Anthony McGregor was the subject of a hearing by the gendarmerie services".

The statement gave no details of Mcgregor's alleged offences and he was released 48 hours later. 

McGregor legal spokesperson Karen Kessler told ESPN the 32-year-old "vigorously denies any accusation of misconduct" while his agent Audie Attar was furious with the allegations. 

"I am irate and putting out a warning loud and clear: Conor McGregor is not and will not be a target for those seeking to score a headline or a payday," Attar told ESPN.

TMZ reported an outlet in France said the alleged incident occurred in a bar.

McGregor was traveling on his yacht with his fiancée, Dee Devlin and he was reportedly set to take part in a 180-kilometre, 24-hour charity water bike race from Calvi to Monaco. McGregor has had numerous run-ins with the law during his career and has not fought since defeating Donald Cerrone in the main event of UFC 246 in January. 

He announced his retirement from UFC in June for the third time in just four years.
