Connor McGregor is in the news again for the wrong reasons. 

This time the former UFC star has been caught on camera punching an old man in the head.

Apparently the punch was because of a dispute over Connor's brand of whiskey. 

It all took place on April 6 at The Marble Arch Pub in Dublin as McGregor offered to buy a round of Proper Twelve for everybody in the bar, the old man refused not once, not twice, but three times. 

Connor took his shot with everybody else and followed that up with a punch to the old man's face. 

As of now the police say no charges have been laid but you can watch the video below.
