THIS is the bone-chilling moment a ruthless cop pins a woman to the ground and holds a loaded gun right up against her temple.

The shocking scene happened as tourists brawled outside a Chinese restaurant in Russia.

Russian National Guard officers were called out to reports of a scrap between tourists on May 31.

The fight had spilled out into the streets of the Khabarovsk – in the country’s far east.

A bystander caught the cops’ intervention on their phone, but it soon escalated into a bloodcurdling scene.

The clip begins with burly officers confronting the brawling tourists as they try to bring order to the streets.

But the crowds aren’t having it, and make an attempt to scrap with the cops.

As the outnumbered officers work to bring the situation under control, a woman suddenly strikes one of the the cops from behind.

She slaps him hard on his ear before taking a step back.

But instead of attempting to restrain the woman by hand, the enraged officer suddenly pulls his gun on her.

The startled woman falls backwards onto the stairs as the cop moves in, pinning her to the ground.

He plants the barrel of his weapon onto her temple for a nerve-shredding split second.

But after a moment, he holsters his weapon while continuing to restrain the woman on the steps.

He then takes handcuffs from a fellow officer as he hauls her away from the scene.

By this point the fight had mostly quietened down, with a few onlookers nervously watching the cops leave.

They barge their way through a few tourists still standing there as they take the woman away for questioning.

According to the Russian state news agency TASS, the cop was later treated in hospital for a burst eardrum.

A Russian Federation Investigative Committee statement said: “A criminal case has been opened for the use of violence against a government official in the performance of his official duties.”

Any offenders could face up to 10 years in jail if they are convicted.

Two other suspects are also reported to have been detained.
