The astonishing footage above comes from the ongoing European Youth Boxing Championship in Zagreb, Croatia.
In the light heavyweight clash between Vido Loncar of Croatia and Algirdas Baniulis of Lithuania on Monday, Loncar had a simply incredible reaction to losing his match.
As you can see at 1:13 in the video above, Loncar knocks the referee to the mat with a quick combination before repeatedly unloading punches once the official is down. The fighter is then finally pulled away.
