There is a lot that can be said about Conor McGregor, to put it as politely as possible, he is a wild child. Now, the Irish MMA fighter is under investigation for sexual assault for the second time this year.

According to the New York Times, a woman alleged that she was attacked in a car parked outside a Dublin pub last week. Witnesses spoke on condition of anonymity owing to Irish laws surrounding investigations. However, the police have yet to launch an investigation into the allegation.

Conor McGregor is already under investigation for a separate case involving another woman who was attacked at a hotel where he stayed in December. The findings of that investigation were sent to Ireland’s prosecutor’s office earlier this year. Now, Conor McGregor is waiting to learn whether he will be charged in that case and worry about the new allegation.

“Conor McGregor is frequently the subject of rumors,” his publicist told The Times. “He emphatically denies any report accusing him of sexual assault.”

This is not the first time Dublin-born McGregor has been involved with law enforcement in recent years. Earlier this year, Conor McGregor was caught on video getting into an altercation with a senior patron of a Dublin pub. During that scene, the man refused to accept McGregor’s offer of what appeared to be whiskey.

A year earlier, McGregor was involved in yet more drama away from the cage. The Irishman was convicted of disorderly conduct after throwing a metal trolley at a bus carrying his UFC rival Khabib Nurmagomedov.

Later in March, the former UFC featherweight and lightweight champion was charged with strong-arm robbery and criminal mischief. Apparently, he stomped on 22-year-old Ahmed Abdirzak’s phone in Miami, US, however the charges were later dropped.
