The prosecutor's office wrote in a statement: "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 police."
"He has been interviewed and released."
McGregor was spotted last night at an extravagant event in the port of Calvi on the French island alongside his fiancée Dee Devlin.
He had travelled to the region to take part in a 180 kilometre water bike race to raise awareness for water safety, but has now been forced to withdraw from the event as a result of his arrest.
The 32-year-old former two-weight UFC world champion had been training and planning for the voyage, which he would have commenced on Saturday alongside Princess Charlene of Monaco.
'The Notorious' McGregor announced in June that he was retiring from mixed martial arts for a third time.
His nickname has proven to be well-earned over the years, as McGregor has been no stranger to controversy throughout his career.
A viral video last year appeared to show McGregor punching an older gentleman in a Dublin pub, and he was convicted of disorderly conduct in 2018 after attacking a bus full of UFC fighters in New York City.
After being let into the Barclays Center in Brooklyn, McGregor and a gang of others attacked a bus leaving the venue after the UFC 223 media day.
The altercation stemmed from another incident involving McGregor's nemesis Khabib Nurmagomedov and fellow UFC fighter Artem Lobov - a friend of McGregor.
He pleaded guilty to disorderly conduct charges and was ordered to complete five days of community service and take a course of anger management classes.
Despite having retired, McGregor also shared on social media his surprise at being drug tested by the US Anti-Doping Agency.
Seemingly amused, McGregor allowed the test to take place aboard his £3 million yacht.
He wrote: "What's going on here UFC? USADA have just arrived to my yacht this morning for testing? I've retired guys!
"But go on then, I'll allow them test me. It's all natural here baby! Forever and always, God Bless."
