This is just insane.

At the European Youth Boxing Championship in Zagreb, Croatia, things took a wild turn.

Two young boxers squared off named Vido Loncar and Algirdas Baniulis. By all accounts, it was a good, hard-fought match.

In the end, they gave Algirdas Baniulis the win. And his opponent wasn't too happy about it.

As Loncar walked over to the ref for the ref to raise the winners hand, he punched the ref square in the face. Knocked him out. Then he continues his assault and punched the official several more times. The ring cleared as he gave the ref a beat-down, then finally help arrived and pulled the crazy boxer off of the ref.

Vido Loncar and his coach have been banned from the sport for life.

Insane video here!
