"AIBA and the entire boxing family have zero tolerance for this sort of behaviour," said AIBA president Ching-Kuo Wu after the Croatian amateur boxer Vido Loncar hit a Polish referee and continued punching him on the floor after losing a youth bout.

He and his ringside trainers have been put on provisional life bans by world body AIBA.

AIBA stated on Wednesday that the organization had barred the light-heavyweight from all possible competition and withdrew his coaches' certifications; for the duration of a meeting of its disciplinary commission.

AIBA declared the president had also told the Polish Boxing Association in a form of a letter that "he had learned that the boxer had allegedly been encouraged by his local club coach to hit the referee."

"I would like to send you my strongest commitments to apply all possible measurements to punish and remove all individuals who brought AIBA and our sport down, as well as to prevent this type of incident from taking place in our competitions ever again," he said.

Loncar punched referee Maciej Dziurgot on the head following primarily returning to his corner when the action against Lithuanian Algirdas Baniulis was stopped.

The boxer then continually punched the referee lying on the floor before being dragged from the ring by his feet grabbed by police. The referee was then taken to a hospital.

A snip of the incident has had more than two million views on You Tube; it happened at the European Youth Boxing Championships in Zagreb on Monday.
