Tensions were high inside and outside of London's SSE Arena during the final press conference of the Conor McGregor-Floyd Mayweather world tour.
Footage obtained by TMZ Sports shows McGregor fans swarming and hurling insults at Mayweather's Rolls-Royce as he was leaving. At one point, the car appears to hit a member of the security staff as he was moving people out of the way.
