This dramatic video shows what happens when a gang of thugs choose the wrong victim to hassle.

The yobs soon learned their lesson when they picked on the wife of a martial arts expert and professional boxer.

A confrontation occurred between Nicolai Vlasenko and three yobs who bothered his wife while he popped to the lavatory at a nightclub that he and his wife were enjoying a night out at. Vlasenko returned to find three men trying to drag his wife into a VIP room of the Russian nightclub which is located in the small South-Western Russian town of Starokorsunskaya.

Taking care of business…

Vlasenko and the gang agreed to continue their “discussion” outside the club, where Vlasenko soon “took care of business, ” flooring one with a left hook and anther with a powerful right hook. Thug number three wades in and receives three walloping blows to his face

An eyewitness to the one-sided fight, 27 year-old Eldar Vinogradoff, said: “When they went outside, the others were there mob-handed. There were at least 10 of them led by the two who thought they were real big shots.

“One of them took off his shirt and started squaring up to the boxer, and I don’t think he even knew what hit him when he went down like a nine pin.

“A second man tried to kick the boxer and he was floored instantly as well. Then a third man joined in, and he was left staggering and on the point of collapsing after taking three blows to the head and not landing once himself.”

With three of their members floored, the gang appears to lose heart and decide to care for their fallen mates, rather than continue the fight.

In a later twist, the gang retained a lawyer, complaining to police that they had been the victims of an unprovoked attack; however, once the police reviewed the CCTV footage, they decided the gang’s claim had no merit.

Vlasenko’s lawyer said: “My client wasn’t prepared to allow them to harass his wife. He was prepared to discuss it in a reasonable manner, but when they resorted to force than he was forced to defend himself with inevitable consequences.”
