Conor McGregor was arrested on Monday after allegedly smashing a fan’s phone outside a Miami Beach hotel.
The Irish mixed martial arts star was held on “strong-armed robbery and misdemeanour criminal mischief”, a Miami Beach police spokesman confirmed.
He was detained on a £5,300 and £755 bonds respectively.
According to the department, McGregor smashed the phone around 5am on Monday morning as the man was taking photos outside the Fontainebleau Hotel.
McGregor, 30, was taken to Miami-Dade jail before having his mugshot taken.
According to an arrest report, McGregor and the fan were walking out of the hotel at the time of the incident.
When the fan tried taking a photo with his mobile, the Irishman “slapped” the phone out of his hand, then stamped on it several times.
McGregor picked up the phone, valued at £750, and walked away with it, police said.
The incident was caught on surveillance video.
McGregor was not arrested at the scene but tracked down to a Miami Beach house where he was understood to staying with his girlfriend, Dee Devlin and children.
The fighter has jetted his entire family out to the States to celebrate his mum Margaret’s 60th birthday.
His arrest comes just days after he finished community service in New York after he was ordered to undergo anger management following his guilty plea deal with US prosecutors for disorderly conduct last July.
McGregor found it “humbling” to do manual labour, said Pastor Clive Neil at the Bedford Central Church, where the fighter worked from Monday through Friday last week.
“He kept on using that word ‘humbling,’ ” the pastor said.
“He was doing physical work – vacuuming, mopping, moving boxes, moving supplies, putting out the garbage and so forth.
“He was quite patient in rubbing down the brass, polishing with spray and a cloth. He has enough strength in his muscles to do that.”
The Irishman has earned millions of dollars from lucrative bouts in Las Vegas and New York since becoming a champion in 2015.
His has an estimated wealth of £24 million.
