TMZ Sports has obtained police body cam footage showing Conor McGregor being handcuffed and arrested at a private home by Miami Beach PD over the cell phone smashing incident.
The footage was shot on March 11 ... hours after Conor got into it with Ahmed Abdirzak outside the Fontainebleau hotel in Miami.
As we previously reported, McGregor went after Abdirzak around 5:21 AM -- snatching the guy's phone and then stomping it multiple times. McGregor eventually left the premises with Abdirzak's phone.
Abdirzak filed a police report and the Miami Beach PD tracked down McGregor at a private residence nearby -- eventually arresting him just before 10 AM.
