A video has surfaced of Conor McGregor appearing to punch an older man in the face at a Dublin pub.

TMZ Sports published the CCTV footage of the April 6 incident on Thursday.

In the video, McGregor allegedly offers to buy the patrons of The Marble Arch Pub shots of his Proper Twelve whiskey brand.

One man seated at the bar can be seen twice refusing a glass from McGregor. The two appear to exchange words before the Irishman throws a left hand at the man's face and two people separate them.

Police have seen the footage and opened an investigation in April, according to TMZ, but it's unknown if they're still looking into the matter. McGregor hasn't been charged.

The former two-division champion was arrested in March when he was accused of smashing a fan's phone. The charges against him were later dropped.

McGregor is also reportedly under investigation in Ireland after a woman accused him of sexual assault in Dec. 2018.

The 31-year-old hasn't stepped inside the Octagon since losing to lightweight champion Khabib Nurmagomedov at UFC 229 in Oct. 2018.
