This is the dramatic moment when hundreds of police officers raided a traveller site in a 3am bust - thought to be one of Britain's biggest ever gun crime stings.
Footage shows the massive police raid at a site in Orpington, south-east London, earlier today.
More than 30 police vehicles were involved, while specialist anti-terrorism officers also assisted in the bust.
Seven people have been arrested, while two people are being supported by specialist from the police's Modern Slavery Team, say the Metropolitan Police.
Commander Kyle Gordon, the lead for the force's firearms operations, told Sky News: 'Any operation where there may be firearms involved requires a lot of planning and a lot of specialist assets.

'As well as the local safer neighbourhood teams and officers that are leading this operation, of course we have our specialist firearms command involved, and a number of public order assets as well.
'Those teams will do everything they can to identify the risk in advance so they can plan around that to minimise the risk - not just to the people on the site and the wider public, but also to themselves as well.'

Elite officers from the Met's Counter Terrorism Specialist Firearms team were also involved, as well as police dogs and specialist search units.
Police are said to have used stun grenades, also known as flash-bangs, during the raid, as one of a number of 'distraction techniques' used to enter the site.
Seven people have been arrested on suspicion of offences including possession with intent to supply drugs, handling stolen goods and burglary while police say they have seized 17 dogs.
Detailed searches of the site, on Star Lane, near Orpington, are taking place this morning.
Commander Gordon said: 'Tackling violent crime remains the Met's top priority and our efforts to prevent serious harm and loss of life on the streets of London have not wavered, including over the last few challenging months.

'This operation clearly demonstrates that every officer – from local neighbourhood teams all the way up to our specialist crime investigators – is focused on bringing those responsible for violence and organised criminality on the streets of London to justice, to keep our communities safe.
'This case was led by local neighbourhood officers in response to local issues, and its success would not have been possible without the support of partners and communities.
This operation has targeted serious and organised crime head on, and will mean the surrounding communities are now safer for those living within them.
'Over recent months we have seen an increase in the number of firearms incidents across London and proactive operations like this are crucial to removing the availability of weapons and drugs on the streets.
'We have now seized dozens of lethal firearms and prevented them entering the hands of dangerous individuals.'
Superintendent Andy Brittain, from the Met Police's South Area Basic Command Unit, added: 'We've been listening to the concerns of the local community and I hope that today's activity shows how seriously we take your concerns and that we do act upon them.

'This is a prime example of why we rely on intelligence and information so much from our communities. It helps us keep your streets safe.
'Local residents may see an enhanced police presence over the next few days and possibly some road closures
