Connor McGregor has been accused of punching a man in the head after the man declined a glass of McGregor’s own whisky, Proper No. Twelve.
On April 6 an incident was reported to the police which occurred following a row in a Dublin bar.
CCTV footage which has been published by website TMZ reveals the 31-year-old MMA fighter punching a fellow drinker, in his 50s, before being escorted away by friends.
Despite the blow to the face, the unruffled victim remained sat in his bar stool.
According to sources, it appears McGregor allegedly attacked the man after when he turned down a free drink from the star. McGregor had been handing out his own branded whiskey in the venue.
CCTV footage shows McGregor by the bar before the incident happened.
Detectives got in contact with McGregor afterwards, however he was not formally arrested.
Ireland’s Directer of Public Prosecutions passed a file on whether or not the star should be charged.
A Garda spokesman stated: “(We) are investigating an incident at a pub in Drimnagh, Dublin, on April 6.
“No arrests have been made. Investigations are ongoing.”
This is not the first incident which has caused McGregor trouble. Last year, McGregor attempted to confront Ultimate Fight Championship rival Khabib Nurmagomedov on a tour bus in New York which resulted in a conviction of disorderly conduct.
McGregor was sentenced to five days of community service and was made to attend anger management classes after appearing in a court New York.
Footage has also emerged from March of McGregor stamping on a fan’s mobile phone in Miami.
The former USC featherweight and lightweight champion was been arrested and charged with strong-arm robbery and criminal mischief over the incident which involved 22-year-old Ahmed Abdirzak’s phone.
