TMZ released a video on Thursday showing McGregor sucker punching a man for not drinking his whiskey Proper Twelve

Police were called following the incident but as of now there have been no arrests made

The attack is the latest from McGregor showing violent tendencies outside of the UFC ring

Surveillance footage shows UFC fighter Conor McGregor sucker punching an elderly man at a bar in Ireland for refusing to drink his whiskey, Proper Twelve.

What Happened

According to TMZ, the incident occurred on April 6. McGregor walked in the bar and lined up cups for bar patrons. McGregor is said to have wanted to buy a round of Proper Twelve for everyone.

After putting the drink in front of the man, he refused to drink it not once but twice. McGregor is seen taking a shot with other patrons before sucker punching the man in the face with his left fist.

McGregor was immediately grabbed by patrons and dragged out of the bar. The attack was reported to police who stated they had opened an investigation in April, but as of now have not pressed charges. It was reported that police in the area have seen the video.

The man attacked in the video appeared to be okay as McGregor’s punch did not even knock him off his stool. The video circulating online has no sound so it is unclear if there were any words exchanged before the punch.

Conor McGregor Smashes Bus Window In New York

The attack is not the first time McGregor has shown violent tendencies outside of the ring. Last year during a media staging event before UFC 223 at Barclays Center, McGregor was caught on video busting out a bus window with a dolly.

McGregor and his entourage began to attack the bus with several fighters on it including Khabib Nurmagomedov. In the video UFC lightweight contender, Michael Chiesa was cut up and bloodied by the glass from the broken window. McGregor ended up dodging felony charges for that incident.

Conor McGregor Smashes Fan’s Phone In Miami

Early this year McGregor was caught on camera breaking the phone of UFC fan Ahmed Abdirzak at the Fontainebleau hotel in Miami. McGregor took Abdirzak’s phone and stomped on it twice before pocketing it and leaving. Surveillance footage of the incident shows McGregor act as if he was going to shake Abdirzak’s hand, but at the last second, he swipes his phone out of his hand before stomping it.

McGregor faced robbery and criminal mischief charges for the attack. The charges were eventually dropped after Abdirzak — who was visiting America from the United Kingdom — decided he did not want to come back to aid in McGregor’s prosecution. Abdirzak also had a civil suit filed against McGregor for just over $15,000 but it was later dropped after reaching a settlement agreement.

McGregor has not been in the ring since his loss to Nurmagomedov at UFC 229 in Las Vegas. It is rumors that talks of McGregor’s next fight could begin after Nurmagomedov and Dustin Poirier fight next month in Abu Dhabi next month.
