Conor McGregor was arrested in Miami after taking a fan's phone and smashing it outside of the Fontainebleau Hotel around 5 am on Monday (March 11). 

According to TMZ, McGregor didn't like that the fan was trying to take a photo of him outside of the hotel. He was subsequently arrested and charged with robbery/strong-arm and criminal mischief over $1,000. This comes shortly after Conor completed his probation for attacking a bus carrying UFC fighters at the Barclays Center last April.
