CCTV cameras outside the bar show how the rest of the group back away after the first three are knocked out cold, instead rushing to the aide of the floored thugs.
The gang later then hired a lawyer to file a complaint to the local police that they had been attacked.
However police have said they are taking no action after the CCTV images showed that the man was clearly acting in self-defence and that he had been on his own against nearly a dozen people who were on the other side.
The lawyer for Vlasenko 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.’
