Quite incredible footage has emerged online from Monday's action in the European Youth Boxing Championships, which shows Croatian light-heavyweight Vido Loncar attacking setting upon a referee with a barrage of punches in a furious reaction to his controversial decision.
Loncar went crazy after being stopped by the official in his clash with Lithuanian contender Algirdas Baniulis, venting his fury in the form of a fierce right hand that left onlookers so stunned they were worryingly slow to intervene.
Baniulis was awarded a stoppage victory that looked premature to say the least and quickly scarpered as Loncar laid into the prone referee, with his coach also particularly static just feet away from the ensuing farce.
Loncar was the home fighter at the tournament in Zagreb in what should have been the pinnacle of his fledging career, but a memorable bout for all the wrong reasons will surely be his last.

The YouTube video at the bottom of the page shows you the damning footage, with Loncar stopped after a standing count before eventually gathering his thoughts and deciding he had more fists of fury to unleash.
A very unfortunate referee gets swiped at the 1.13 mark of a video which is destined to go viral, with eight long seconds passing before he's mercifully yanked from the ringside judge.
