The arrest report goes on to add further detail that McGregor 'slapped the phone out of the man's hand and then stomped on the phone several times.' He is then said to have picked up and walked away with the phone, the report adds.
McGregor was being held on $12,500 bail.
McGregor, 30, was charged with felony strong-armed robbery and criminal mischief, according to Miami Beach police.
The incident was captured on surveillance video.
Conor McGregor was reportedly booked in a Miami-Dade County jail on Monday. The Irishman just recently completed community service in NY after he attacked a UFC bus last April that also landed him in jail before he eventually pled down to a single charge of disorderly conduct. The plea required McGregor to keep a clean record for one year, as well as serve five days of community service and attend an anger management program. He is yet to confirm a return fight after losing to Khabib Nurmagomedov previous year, but has been touted to fight Donald "Cowboy" Cerrone in a popular UFC match-up.
