This is the moment the suspected Moscow massacre terrorists are frogmarched blindfolded into a building for interrogation over the concert hall shooting.
The suspected killers are held tightly by security guards as they are taken out of vans and brought to the Russian Investigative Committee for questioning.
Separate footage shows the arsenal left behind by the gunmen who staged the bloodbath at the Crocus City Hall that left at least 137 people dead.
Officers said they found four sets of combat ammunition, more than 500 rounds of ammunition and 28 magazines at the scene of the massacre.
Two Kalashnikov assault rifles were also recovered from the concert hall.

The attack – which happened in Krasnogorsk, on the outskirts of Moscow on Friday night- is the deadliest attack on Russia in years.
The four suspected terrorists were seen arriving in an unmarked white van before they entered the concert hall at around 8pm.
Videos previously emerged on social media of the suspects being arrested – with one shaking on his knees and apparently confessing to carrying out the attack.
Photographs and the names of four suspects have also been released by the Russian media.
Shots were first fired at people waiting in the foyer before the killers made their way to the concert hall area.
After shooting at concert-goers the suspected ISIS terrorists set the building on fire, causing the roof to collapse.

Islamic State claimed responsibility for the attack and it is thought the men were members of for ISIS-K, an offshoot of the terrorist organisation.
The group released a sickening 90-second selfie after the attack that is too graphic for MailOnline to share.
The clip, described by the terror group as ‘exclusive scenes… of the bloody attack on Christians yesterday in the city of Krasnogorsk in Moscow’, begins with one terrorist holding a knife running into the main hall of Crocus City Hall.
The man filming the video twice says: ‘Bring the machine gun. Kill them and have no mercy on them.’
Another man carrying what appears to be a yellow and black machine gun then runs into the hall and begins firing wildly in all directions.
The gun appears to match up with images released by Russian authorities of the aftermath of the attack.
The gunman filming the sick attack can be heard saying: ‘The infidels will be defeated, God willing. God is great. The infidels will be defeated. We went out for the sake of God and to seek His religion.’

The four heavily armed men are then seen slowly walking away from the entrance to the main hall.
It has been alleged that one of the suspected killers staked out the Crocus City Hall venue more than two weeks ago.
This was almost exactly at the time the US and UK embassies warned of an impending risk of a strike in the Russian capital.
The revelation emerged as footage was revealed purporting to show dictator Vladimir Putin in his office as he was told of the atrocity.

Another victim was Natalia Zudina, 44, a graduate of the Ural State Economics University, who was originally from Yekaterinburg.

The group en route to Ukraine were reportedly apprehended by Chechen fighters loyal to close Putin ally and warlord Ramzan Kadyrov
Russian President Vladimir Putin announced March 24 as a day of national mourning in an address that was televised to the country, according to Russian news agency Tass.
Despite ISIS’s claims of responsibility, Putin was quick to blame Ukraine for the horror attack.
But the US was quick to rebuff these allegations. ‘ISIS bears sole responsibility for this attack. There was no Ukrainian involvement whatsoever,’ National Security Council spokeswoman Adrienne Watson said in a statement.
