A young woman was violently attacked at a nightclub and later went to hospital to be treated for her injuries - only to be stunned to discover the doctor was the same man who she alleged had assaulted her.
The medic is seen in a shocking video battering Anastasia Dmitrieva for a second time in the treatment room of the hospital in Neryungri, eastern Russia.
The first attack happened late at night in the club and she went to hospital for treatment the next day, when she encountered the doctor for a second time.
The same doctor who the woman claimed assaulted her in the nightclub, then treated her for her injuries.
In the video, the medic begins hitting the woman, telling her witnesses will prove she attacked him first.
In the footage the doctor can be heard saying: 'Many witnesses will prove that you were the first to attack me.'
He threatened her that she faced 'jail' if she pursued a complaint against him.
A bespectacled middle-aged nurse appears to be embarrassed by his violent behaviour yet tries unsuccessfully to block the camera shooting the horrific incident.
The senior doctor named as Vladimir Naumov has been fired for his violent attacks by the regional health ministry.
Ms Dmitrieva, believed to be aged 20, went to the hospital so that her injuries could be registered, allowing her to make a complaint to police over the nightclub incident, as well as to get treatment for her wounds.
The senior doctor was named as Vladimir Naumov and he claimed he was defending a midwife who was attacked in the nightclub.
He admitted he was 'angry and full of adrenaline' but the decision was made to fire him.
Health chiefs rejected the doctor's explanation that at the nightclub he had been defending a midwife who was attacked by a gang of women.
Naumov said, "I couldn't stand there and watch this massacre. Any man would have tried to stop such a fight."
He admitted that at the hospital he had been angry and full of adrenaline seeing the woman again but a decision was made too fire him over his behaviour.
"I was provoked for the sake of filming this video," he claimed.
"I have been working here for one and a half years. During that time, I saved many people and now everything I did is ruined by this video."
His unnamed chief doctor is facing an investigation over employing a man unsuited to be a doctor.
