Former UFC division champion, Conor McGregor is being investigated for alleged sexual assault in Ireland. Irish law prohibits names of criminals involved in a sexual assault being released. However, stories began to surface in January about an Irish sports star that was connected to an alleged rape. Now we know it's none other than UFC's biggest star Conor McGregor.

McGregor has been arrested by law enforcement, but he is not facing any charges currently. The arrest is in relation to an event in January, leading to police to question him, but eventually releasing him.

This is the latest rough patch in McGregor's controversial career. He's been arrested over the years, including for his latest attack on a UFC bus in Brooklyn. Just this month, he was caught breaking a fan's cell phone. McGregor was even suspended for a post-fight brawl at UFC 229.

Conor McGregor announced his retirement on social media

McGregor tweeted out his surprise retirement, just hours before the New York Times released a story reporting the alleged sexual assault investigation. He wished his former colleagues well and now joins other legends already in retirement. Rumors have surfaced alleging that McGregor is rumored to have fathered an illegitimate child in Ireland. He strongly denies these rumors.

McGregor has two children with his longtime girlfriend Dee Devlin.

Reports claim the alleged assault took place at the Beacon Hotel in Dublin, a place he often frequented. He was last there in December. The police ended up gathering evidence and recovering security camera footage from the day in question.

McGregor's team denies retirement tied to assault allegation

McGregor's spokeswoman, Karen Kessler, publicly denied that his retirement is tied to this alleged assault. Kessler said he would return to fighting in an environment that respects his talent, skill, and dedication to the sport. McGregor has not won a professional combat fight since 2016.

McGregor lost against Floyd Mayweather in a 2017 boxing match.

The controversial superstar broke UFC pay-per-view records on his way to becoming the first two-division champion in history. Despite losing to Mayweather, his pro boxing debut earned him $100 million and came close to breaking boxing's PPV record for buys. Some fans believe this is just a publicity stunt by the superstar MMA fighter. We will have to see how this incident impacts his future as a fighter in any capacity.
