A drunken demobbed Russian soldier has boasted about how he ripped a piercing from a terrified teenage boy’s nose to “teach him a lesson.”

Graphic footage of the attack on a train – filmed by the soldier – shows one teenage boy covered in blood after a ring has apparently been pulled from his nostril.

A second boy looks terrified as he struggles to remove his own piercing before the ex-soldier attacks again.

Throughout the footage, the former conscript can be heard ranting drunkenly at the boys on the train in Moscow Oblast.

Police later named the soldier as 20-year-old Alexander Zhuravlev.

Zhuravlev posted the footage on social media but when he was criticised he boasted he had already “cleared the matter up” by talking to local police.

Police, however, say they are investigating the attack and deny any deal with the former conscript.

They had later arrested Zhuravlev who had been out celebrating his demob from the Russian armed forces.

He admitted that he had been drunk as the train neared Istra station and he had spotted the two teenagers and decided to “teach the guys a lesson”.

It speculated that the man was a Ukraine war veteran who had completed his stint after he admitted he was partying because he had been recently demobilised from the army, but this was not confirmed by authorities.

The attack follows another violent attack recently also on a train with two children beaten up by another passenger because one of them had a backpack that was yellow and blue – the colours of the Ukrainian flag.
