UFC fighter and novice boxer Conor McGregor has made world headlines once again for the wrong reasons after one of the more bizarre incidents in recent combat sports history.

McGregor and a gang of his friends were caught on camera attacking a bus in New York that contained UFC fighters in it yesterday.

It is thought that McGregor was looking to retaliate for actions alleged of one of the fighters in the bus towards a McGregor team-mate earlier this week.

The incident took place following a media day yesterday at the Barclays Center in Brooklyn where McGregor and his team turned up unannounced.

The following footage obtained by TMZ YouTube shows an alternate angle of the crazy scenes that ensued:

Quite incredible scenes that have landed McGregor in significant trouble already.

He turned himself into the police last night and it has been widely circulated this morning that he has been charged with multiple accounts of assault stemming from the above incident.

It is not clear at this point if McGregor will face legal action from those affected but UFC President Dana White has strongly suggested that McGregor will be receiving lawsuits from various parties.
