A harrowing video has emerged of a drunk government worker savagely beating a cloakroom attendant after being refused entry to the bar where she worked.
The 24-year-old man had been turned away from the bar in the city of Rostov-on-Don in south-west Russia's Rostov Oblast region.
Security guards said he was already drunk and that he walked away after he was refused entry to the bar.
But horrific CCTV footage from the cloakroom shows him coming back armed with a concrete and metal sculpture of a flower he had found outside.
In the short clip, the man opens the side door to the booth and rushes in, using the heavy sculpture to beat 52-year-old Elena Zhukova over the head.
Passersby realised what was happening and one rushed into the booth to restrain the assailant.
Ms Zhukova was taken to the hospital with severe injuries and the attacker was arrested.
Her son, who did not give his name, said: 'She had a trauma to the brain so she had to have brain surgery.
'Now she is getting better, but still has a patchy memory.'
Police say they are still investigating the incident.
It is not clear whether the suspect, who was not named, was held in custody.
It is also unclear why the assailant's anger was directed at the cloakroom attendant instead of at the security guards who turned him away.
