A man from Barnet is among 14 people who have been arrested following a series of dawn raids targeting one of the UK’s most "high profile" organised crime gangs.
Since last night, around 200 police officers have carried out search and arrest warrants at 22 addresses across the capital.
The operation, codenamed Octopod, has seen a total of 14 people arrested, some with known links to violence and other serious crime spanning many years.
Many items were also seized from addresses, including a handgun, six shotguns and £150,000 in cash.
Detectives have worked to follow money trails linking property ventures and crime over many months. Some of those arrested are believed to be behind the finance arm of the crime gang, involving working as accountants, mortgage brokers and property developers.
Among the 14 arrested is a 51-year-old man from Barnet who is suspected of money laundering and fraud.
He is currently in custody at a central London police station.
Detective Chief Superintendent Tom Manson, of the MPS specialist, organised and economic crime command, said: "We believe we have arrested members of the most long-established and high-profile crime gang in London.
"The links between this gang and serious and violent crime are well documented as is their strong influence across London, and, we believe, connections to criminals across Britain and Europe.
"We believe they are responsible for a multi-million pound criminal business; laundering the profits from crime and using this money to commit other money-spinning offences. This is cash which can be used to fund further crime and provide luxurious lifestyles.”
