It's April 2020, and the Metropolitan Police are overwhelmed with messages hacked from the EncroChat network.   Buried among the millions of texts and photographs, are the outlines of a murder plot. An anonymous EncroChat user is trying to source a gun and some ammunition for a drive by shooting.   Will the police discover the messages before it’s too late? And will they be willing to risk the secrecy of the entire EncroChat operation by arresting someone on EncroChat evidence alone?  Presenter: Mobeen Azhar

Catching the Kingpins: 2. Threat to Life

Gangster presents...   A 6-part true crime podcast documenting the biggest organised crime bust in British policing history. It happens in 2020 when police in France penetrate an encrypted phone network called EncroChat. According to police, the phones were used exclusively by criminals.  
 
For over two months, police forces across Europe were reading the secret communications of major league criminal networks.  The Metropolitan Police, working with the National Crime Agency and other forces, used this information to uncover the workings of organised crime groups. 
 
“It was like being in a room with them and they are talking freely, and they don't see you there,” says DCI Driss Hayoukane, the Senior Investigating Officer who led the Met’s EncroChat operation. 
 
Police went public about the EncroChat hack in July 2020. This is the first time that the inside story of some of the Met’s biggest EncroChat cases has been told to a broadcaster. 
 
Talking exclusively to BBC Sounds, police officers reveal how they used the gangsters’ messages to uncover arms dealing and expose murder plots as well as major drug trafficking and money laundering operations. Stories featured in the series include:  - A murder plot unearthed by the Met in a joint operation with South Wales police. 
- Two apparently legitimate businessmen, living in a Buckinghamshire village, whose wealth really came from cocaine trafficking and major league money laundering, 
- A corrupt police officer who was working for a notorious London crime group.   
At a time when the Metropolitan Police Service has been in the headlines for all the wrong reasons, it’s a rare story of an extraordinary success: nearly 1000 arrests; over 400 convictions; the seizure of £19 million in cash, three tonnes of Class A and B drugs and 49 guns.  
 
But presenter Mobeen Azhar does not shy away from what have been difficult issues for the Met police: an officer from the Met’s anti-corruption unit speaks for the first time about how hacked EncroChat messages helped to expose the worst case of police corruption he had ever seen; and Mobeen asks the officer leading theMet’s EncroChat investigation about the experience of being an ethnic minority officer in a force found to be institutionally racist.

True crime

The EncroChat hack has given the police unprecedented access to the secrets of organised crime. Nearly four years on from the hack, the detective who led the Met’s EncroChat investigation, DCI Driss Hayoukane, reveals what the police have learnt about OCGs which they didn’t know before.  Presenter Mobeen Azhar hears about the impact of the EncroChat operation from Driss and from the National Crime Agency. There have been thousands of arrests, 200 threats to life averted and tonnes of drugs seized. But has taking out the kingpins cut crime?

Catching the Kingpins: 6. Final Reckoning

The truth unearthed about Met police officer PC Kashif Mahmood is stranger than an episode of the fictional drama Line of Duty.

But he was secretly working for an OCG in east London.  A detective from the Met police’s anti-corruption unit talks publicly for the first time about the most brazen case of corruption he’s ever seen.  Presenter: Mobeen Azhar

Journalists David James Smith and Joseph Cox explain what their investigations into the company reveal.  Plus, why an expert in cryptography thinks the whole EncroChat operation could fall apart on a legal technicality.  Presenter: Mobeen Azhar
