After the man rejects the glass both times, McGregor then pours a round for others in the venue.

The video cuts to a few minutes later with McGregor gesticulating with his arm.

It's unclear whether he and the man at the bar are exchanging words, but an agitated McGregor swings with his left hand, appearing to strike the man on the side of the face.

According to TMZ, Police are aware of the video and are still investigating but say no arrests have been made as yet.

The incident is just the latest in a long list of controversies surrounding the Dublin-born grappler.

Later in the year, McGregor's loss to bitter rival Khabib Nurmagomedov descended into chaos after a mass brawl involving member's of both fighters' teams following match.

Both men were fined and banned following the Las Vegas incident.

Earlier this year, McGregor was involved in an altercation where he reportedly took a man's phone and smashed it on the ground, although criminal charges were eventually dropped.

Following the Nurmagomedov debacle last October, it is unclear when McGregor is expected to return to action in the UFC.
