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?

The truth unearthed about Met police officer PC Kashif Mahmood is stranger than an episode of the fictional drama Line of Duty. And it was evidence unearthed in the EncroChat operation which made him plead guilty.

PC Kashif Mahmood had won five awards for his outstanding service as a police officer. 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.

Little is known about who invented the EncroChat network and who owned it. Even the police who investigated the criminals using the network, know little about who’s behind it.

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.

In the wealthy village of Denham in Buckinghamshire, Lee Hannigan and Harry Hicks-Samuels play the part of successful businessmen really well. Hannigan has a car garage, a mansion with a Ferrari on the drive and a place in Dubai. Hicks-Samuels is only 27 but has a watch business and flat in a luxury development.

But the secrets of where their money really comes from are on their EncroChat phones.

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?

Police across Europe prepare for a top-secret operation: the hacking of EncroChat, an encrypted phone network favoured by organised crime groups.

EncroChat’s server has been discovered in northern France. The French police are planning to secretly inject some code into the users’ next software update. If it works, police could be reading the criminals’ messages for weeks.

At the Metropolitan Police in London, DCI Driss Hayoukane is summoned to a confidential meeting where he hears about the plan. He realises this is a once in a lifetime opportunity and decides to put his retirement on hold.

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 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. 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 the Met’s EncroChat investigation about the experience of being an ethnic minority officer in a force found to be institutionally racist.

Despite the landmark trial of 2004-05 leading to several convictions for the murder of Charlene and Letisha - the gang murders in the city continued. What more could be done to tackle the violence?

In the final episode in the series, we look at how a combination of one man’s brilliant gang mediation and West Midlands police’s Operation Ventara slowly started to turn the tide and begin the process of restoring peace to the city of Birmingham. At the same time as the police were making inroads into dismantling the Burger Bar Boys’ operation in the city, the gang’s ambitions had begun to stretch to neighbouring cities – even as far as Aberdeen. The absence of crack cocaine and lack of rivals in other cities made spreading their net wider an easy task, but law enforcement continued to fight back.

We’ll hear from an undercover police officer who was sent into Northampton to join the city’s Burger Bar Boys offshoot there, and how developments in ballistics allowed police to trace the movement of guns like the MAC-10 as they were passed around the country from one gang member to another.

We conclude the series by looking at where things stand now in the city. What became of the convicted gang members, and how the Burger Bar Boys name still echoes around the streets of Handsworth to this day. We will hear how the families who lost loved ones feel as they reflect on the events of the last few decades, and how back in the Burgers’ home territory of Handsworth, there is at last some optimism.

It’s late 2004 and the buzz of police helicopters and sea of armed police around Leicester Crown Court creates a tense, intimidating atmosphere as one of the biggest murder trials of the decade gets underway. West Midlands police have the men they believe responsible for the deaths of Charlene Ellis and Letisha Shakespeare ready to stand trial for their crimes. But this was not going to be an easy conviction. Detectives had identified 75 people they believed could provide key evidence - yet all of them refused to testify. Then a break came from a man in prison who told prison officers he had seen some of the men in the car involved in the shooting. The problem was - he needed to remain anonymous, and this would involve a legal first.

The trial would go on to last the best part of six months - at that point it was the longest trial in British history and there were several times when it threatened to collapse. Meanwhile, the Burgers were doing everything they could to find out the identity of the secret witness, using extreme violence and intimidation to uncover the name of this faceless man trying to put them behind bars. For the families of Letisha and Sophie and West Midlands police - would they get to witness the killers being put behind bars and finally bring the Burger Bar Boys’ reign of terror to an end?

As the new century begins, the gang war in Birmingham intensifies. Bloody retaliation follows each shooting and we eventually reach the point where there is no longer any trace of mutual respect between the gangs.

A gang war that began with vintage and adapted firearms had reached the point where submachine guns were the go-to weapon of choice. On January 1 in 2003, a group of innocent teenage girls were getting ready to celebrate the arrival of the new year together at a party in the heart of the Johnson Crew’s territory. Meanwhile, the Burgers were after revenge following the death of member Yohanne Martin and the failed attempt on the life of their ‘Godfather’, and they knew there would be Johnsons at the party.

The tragedy that would unfold was to draw the world’s attention to the city of Birmingham. It was now 4am, the party was in full swing, and the girls had stepped out for air. A car pulled up and a 9mm pistol and MAC-10 machine gun - a weapon capable of firing a thousand rounds a minute - were fired into the crowd. Letisha Shakespeare and Charlene Ellis were killed instantly. Charlene’s sister Sophie was seriously injured and their friend Cheryl also suffered a bullet wound.

In this episode we will hear the powerful and heart-breaking testimony of those closest to the girls and we hear how the girls’ senseless deaths became the turning point in the government’s response to gang violence. With the spotlight on Birmingham, the pressure was mounting on West Midlands police to bring those responsible to justice…

With the Yardie threat receding, the Johnson Crew and the Burger Bar Boys vied for dominance in the city. Guns became the weapon of choice, and nowhere felt safe; even the celebratory Handsworth Carnival turned into a scene of extreme gang violence. Territorial battle lines were drawn, with the Johnsons claiming the B6 postcodes of Lozells & Aston, and the Burgers controlling the B21 Handsworth area. It was in the 1990s that the names of key players began to emerge through the smoke of gun barrels. Known by their street names, the powerful and intelligent leader of the Burgers was dubbed 'the Godfather,' while others like S1, Little Dee, Charmer, and Honey Monster struck fear into the hearts of their rivals. Rumors circulated that S1 was so powerful that he was impervious to bullets due to a witchdoctor's protection spell, allowing him to survive multiple gunshot wounds.

At the heart of the Burgers' operation was Raleigh Close in Handsworth, a maze of alleys and connecting ring-roads offering multiple escape routes from their rivals and the West Midlands police. As the millennium came and went, tit-for-tat murders increased, putting a strain on the area's City Hospital, which constantly dealt with new types of trauma injuries and tried to keep the body count down. Crucially, it was the murders during this period that revealed the power of the rival gang leaders. Not only were they capable of cold-blooded murder, often in broad daylight, but they could be seen by multiple witnesses, and still, the public was too terrified to step forward and secure a conviction. As their rivalry escalated into all-out war, the gangs intensified their recruitment efforts, targeting neighbourhood schools to bolster their growing number of foot soldiers and street dealers. For the Burgers and the Johnnies, what would happen next would have global repercussions...
