UFC star Conor McGregor punched an elderly man in the side of the head at an Irish bar back in April. Video of the incident shows Conor walk into The Marble Arch Pub in Dublin and attempt to buy everyone at the bar a shot of his whiskey, Proper Twelve.
One of the men at the bar turned down the shot multiple times. That set off McGregor and he is seen punching the man in the side of the head before being escorted out.
