Two kilos of cocaine, jewellery and high-value watches were found in specially-built ‘hides’ concealed in vehicles.
They were found as part of one of the Metropolitan Police’s largest operations to tackle serious and organised crime.
The raids were made possible after the National Crime Agency and European forces managed to get inside a formerly secure phone system called EncroChat in an operation dubbed Operation Venetic.
EncroChat is a messaging system, which is similar to WhatsApp and is only pre-loaded onto special phones which have to be specially bought.
The Met’s operation has resulted in £13million in cash seized and the arrests of some of London’s most dangerous criminals.

Three hides were found in transit vans used by the suspects arrested as part of the operation.
One of them was built into the floor of the van’s rear and opened by remote control.
Two of the others looked like an electrical generator box that you might see in the back of any tradesman’s van and were covered in tools and other building equipment.
These boxes had complex methods of being opened, the officers discovered during the investigation.
Firstly they had to be powered up using an electrical transformer device and a specially-made key fob was required to engage a hydraulic lock inside the box.
Deputy Assistant Commissioner Graham McNulty said that to conceal drugs, weapons and the proceeds of their crimes, criminals go to great lengths.
He added that officers regularly encounter hides in vehicles and properties.
He said: ‘Some are basic, and some are specially constructed at significant cost to stash away evidence and illegal profits.
‘Our officers instinctively look for evidence in places you wouldn’t think to look and have the knowledge and expertise to gain access to even the most sophisticated hides with complex locking mechanisms.

‘These people think their wealth is untouchable, and the sole motivation for people involved in serious organised crime is money.
‘That is why, as part of these investigations, we will look closely at their finances and use all the resources and legislation available to us to take everything they have obtained using criminal funds away from them, and bring them to justice.’
Criminals paid £1,500 for a six-month contract to use the specially-bought phones and could send a ‘kill code text’ which wiped everything on the customised Android handset.
Investigators found 60,000 users worldwide and around 10,000 users in the UK alone on EncroChat – the sole use was for coordinating and planning the distribution of drugs, guns, dirty cash, money laundering and plots to kill rival criminals.
Top level criminals could be monitored speaking freely about their operations and plans, thinking their network could never be cracked.
One of the Met’s operations seized £5million in one go – which is the force’s largest ever single cash haul.
Commissioner Cressida Dick said: ‘This operation is the most significant activity, certainly in my career, we have ever carried out against serious and organised criminality across London.
‘Organised crime groups have used encrypted communications to enable their offending.
‘They have openly discussed plots to murder, launder money, deal drugs and sell firearms capable of causing atrocious scenes in our communities.

‘They were brazen and thought they were beyond the reach of the law. Organised crime does not respect geographical boundaries.
‘Those responsible for it adapt quickly and take advantage of every opportunity.
‘This operation has enabled us to target those at the top of the hierarchy and individuals we have known about for years but have not been able to tackle head on.
‘This offending has a direct impact on our communities – those involved appear to have an air of respectability, but their actions leave a trail of misery and are inextricably linked to the violent scenes we see play out on our streets.
‘Our investigators, intelligence analysts, firearms officers, Territorial Support Group and our local officers have worked day and night over the past two months to progress our investigations as part of this operation.
‘Through this work with our international partners, we have significantly developed our understanding of organised criminality in London and the ways in which some of our most prolific and dangerous offenders operate.
‘This is just the beginning, there are many more people we are investigating. We know who they are and we have seen what they are doing and who they are doing it with. We will not rest until they have seen justice.’
