Entertainment Sports Conor McGregor Reportedly Hit a Man for Refusing a Shot of His Whiskey It's unclear if anything was said between the pair By Claudia Harmata Published on August 15, 2019 04:15 PM Share Tweet Pin Email Photo: Steve Marcus/Getty Conor McGregor appears to be at the center of yet another altercation. On Thursday, TMZ Sports obtained a video from April 6 that purports to show the Irish UFC star, nicknamed “The Notorious,” punch an elderly man in the face when he refused to take a shot of McGregor’s Proper Twelve whiskey. In the video, McGregor, 31, is reportedly seen approaching a group of men sitting at the bar at The Marble Arch Pub in Dublin, Ireland. He proceeds to order shots of his whiskey, handing them down to the group. One man refuses the shot, according to TMZ, moving the glass away when McGregor places it in front of him. The UFC fighter forcefully places another glass in front of the man, who moves it away again, shaking his head.

It’s unclear if anything was said between the pair, but McGregor can be seen fist-bumping and cheering with a group of men further down the bar. Then, without warning, he punches the elderly man square in the face. Two other men instantly pulled McGregor away and out of the bar. McGregor’s rep did not immediately respond to PEOPLE’s request for comment. The man who was punched seemed to show little reaction to the blow in the video. TMZ reported that police opened an investigation back in April when the incident occurred, though it’s unclear if it is still active and there were no reports of McGregor being charged. An Garda Síochána, Ireland’s National Police and Security Service, declined to comment to PEOPLE.
