This is the moment the suspected terrorists of the Moscow massacre are marched blindfolded into a building for questioning about the concert hall shooting.
The suspected killers are held tightly by guards as they are taken from vans and taken to the Russian Investigative Committee for questioning.
Separate images show the arsenal left behind by the gunmen who staged the Crocus City Hall massacre, which 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 took place on Friday evening in Krasnogorsk, on the outskirts of Moscow – is the deadliest attack on Russia in years.
The four suspected terrorists were seen in an unmarked white van at around 8pm before entering the concert hall.
Videos of the suspects being arrested – with one shaking hands and apparently confessing to carrying out the attack – previously emerged on social media.
Photos and the names of four suspects have also been released by Russian media.
Shots were first fired at people waiting in the foyer before the killers moved to the concert hall.
After shooting at concertgoers, the suspected ISIS terrorists set the building on fire, causing the roof to collapse.

Islamic State has claimed responsibility for the attack and it is believed the men worked for ISIS-K, an offshoot of the terrorist organization.
The group released a sickening 90-second selfie video of the attack, which is too graphic for MailOnline to share.
The clip, described by the terror group as “exclusive scenes… from yesterday’s bloody attack on Christians in the city of Krasnogorsk in Moscow,” begins with a terrorist running into the main hall of Crocus City Hall with a knife.
The man filming the video twice says, “Bring the machine gun. Kill them and have no mercy on them.”
Another man carrying a yellow and black machine gun runs into the hall and starts shooting wildly in all directions.
The weapon appears to match 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 wonderful. The unbelievers will be defeated. We went out for the sake of God and to seek His religion.”

You then see the four heavily armed men slowly walking away from the entrance to the main hall.
It is claimed that one of the suspected killers staked out the location of Crocus City Hall more than two weeks ago.
This was almost exactly as the American and British embassies warned of an imminent 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 about the atrocity.

More than 140 people are said to have been killed in the attack in Moscow
Suspect Shamsuddin Fariddun, from Tajikistan, was captured on camera by a photographer at Crocus Town Hall on March 7, it is claimed.
The attack killed nearly 140 people and injured about 150 others.
One of the victims has been confirmed by the Russian Health Ministry as 42-year-old former beauty queen Ekaterina Novoselova.
Another victim was Natalia Zudina, 44, a graduate of the Ural State Economics University, who was originally from Yekaterinburg.
An eight-year-old boy, who is in critical condition in hospital, is listed among the injured.

The group heading to Ukraine was reportedly captured by Chechen fighters loyal to Putin’s close ally and warlord Ramzan Kadyrov.
Russian President Vladimir Putin announced March 24 as a day of national mourning in a televised speech to the country, according to Russia’s Tass news agency.
Despite ISIS’s claims of responsibility, Putin was quick to blame Ukraine for the horror attack.
But the US was quick to dismiss these accusations. “ISIS bears sole responsibility for this attack. There was no involvement whatsoever from Ukraine,” National Security Council spokeswoman Adrienne Watson said in a statement.
