Irish MMA fighter Conor McGregor says he regrets actions that led to his latest US court appearance.

The 29-year-old is facing three counts of assault and one count of criminal mischief over an alleged attack on a UFC bus.

He is accused of throwing a metal dolly cart through the window of the bus, carrying contestants during a media event, in April.

McGregor is also accused of throwing a punch at "security detail."

The MMA star could face between seven and 11 years in prison if he fights the charges and loses.

It is understood he is negotiating a plea deal with prosecutors - and is due back in court on July 26th.

McGregor spoke to the media, after a very brief court appearance in Brooklyn on Thursday.

Fellow Dublin fighter Cian Cowley was also charged and bailed in relation to the same case.

On Tuesday, McGregor tweeted a photo of himself and Cian in front of a jet before their flight to NYC.

McGregor has not fought in the UFC in 20 months and has been stripped of both his lightweight and featherweight titles.
