Conor McGregor New Arrest Video from Cell Phone Incident

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.

In the footage, McGregor is cooperative and quiet as cops instruct him to place his hands behind his back while they place him in handcuffs and put him into a squad car to be transported to jail.

McGregor has since been charged with felony robbery and misdemeanor criminal mischief. If convicted on all counts, Conor faces up to 6 years in prison.

Conor has pled not guilty on all charges. A trial is scheduled to begin in May.
