The charges Conor McGregor was facing in Miami for allegedly taking and smashing a man's mobile phone have been dropped.

McGregor was facing one charge of strong-armed robbery and one charge of misdemeanour criminal mischief, but Florida prosecutors opted to drop both during a hearing on Monday.

Irishman McGregor was arrested on March 11 and, according to a police report filed at the time, he allegedly grabbed a man's phone while he was trying to take the former UFC champion's picture as he left a Miami hotel.

Police then reported that McGregor smashed the phone by stamping on it multiple times, then left with the phone.
