See how the Croatian boxer mercilessly beat a judge in the ring

Young Croatian boxer Vido Potter infamously marked the European Championships for juniors in amateur boxing, which is being held in Zagreb. 
TKO in the second round he defeated the Lithuanian Algirdas Baniulis and after the Chief Judge counted three times, and this is something the Potter obviously disagreed. 

At the time the judge should have declared a winner Potter approached the judge knocked it and then continued to beat while he lay on the floor. Soon they responded by stewards and award judges, and some of them managed to catch Loncar leg and literally drag him out of the ring. 

Regardless of whether the judge his decision damaged young boxer or not, it was a shameful and at least unsportsmanlike, a move which is not a place in sports arenas and it is expected that Potter is likely to be punished lifetime ban from practicing amateur boxing.
