In the sun-drenched port city of Marseille, a dark underworld thrives, where drug gangs wield power over deprived neighborhoods and recruit vulnerable children to do their bidding. A recent investigation by the BBC has uncovered the chilling reality of how these gangs lure young people with promises of easy money, only to trap them in a cycle of violence, exploitation, and murder.

The Note That Sparked a Rescue

In 2022, a woman in Marseille bought hashish from a teenage dealer on a housing estate. Along with the drugs, she received a note: "We're being held captive and need help. We are 15-years-old." The boy was one of two teenagers held by a gang after they approached the group looking for work. What followed was a nightmare of beatings, forced naked dancing for blackmail, and rape. The boys eventually tried to escape from a second-storey window, injuring themselves. One managed to flee, while the other was caught, beaten, and stabbed, but survived. Six men have since been sentenced for their roles in the ordeal.

This harrowing story is just one example of the grip that drug gangs hold over parts of France's second city. Beyond the picturesque tourist spots, neighborhoods like Quartier Nord are controlled by ruthless criminal organizations, most notably DZ Mafia.

DZ Mafia: A Brand of Fear

DZ Mafia emerged from a bloody turf war to become one of France's most feared gangs. Its name references the official internet country code for Algeria, where one of its founders, Mehdi Laribi, was detained earlier this year. The gang rose to prominence in 2023 by becoming the first French gang to release video statements, using social media to market itself as a brand, according to Dimitri Zoulas, head of France's anti-drug trafficking unit.

The gang's reach extends beyond Marseille. In July, the mayor of a nearby town was placed under police protection after intelligence suggested he was a target. In an online video, six masked men denied DZ Mafia's involvement.

France's expanding illegal drug market has fueled the gang's growth. Cocaine users are expected to reach two million soon, up from 600,000 in 2017, and drug smuggling generates €7bn annually, involving 200,000 people. Many of those distributing drugs are children, with over 10,000 minors involved in trafficking during 2025.

Recruiting the Vulnerable

DZ Mafia is now recruiting young people from across France, not just to sell drugs but to carry out kidnappings, torture, and murder. These children are seen as easy to corrupt and expendable by the kingpins who control them from prison or abroad.

Karine Brouillard, a mother from northern France, knows the human cost all too well. Her son Hugo first ran away at 15 and was later found in Marseille with money and cannabis. In 2023, he told his parents he had a holiday job at a restaurant near Marseille. Three weeks later, a doctor called: Hugo had been shot in the head. Police suspect he was involved with a gang.

"They destroy families," Karine says of the gang leaders. "Little sisters, little brothers, grandparents. But then, I don't think those people have a heart, really."

Life Inside the Gang

The BBC team gained rare access to Quartier Nord with the help of resident Fadella Ouidef, a mother of four. Within seconds of entering a housing estate, they were cornered by gang members manning a checkpoint. "Lately, the gangs have been very aggressive," Fadella explains. "What we simply try to do is make sure our young people understand what's happening is wrong."

Camil, a 20-year-old who claims to have left DZ Mafia, described how the gang recruits: "They know how to get inside your head. Whatever you want, they give to you." This can range from cars and apartments to drugs and prostitutes. "You feel loyalty because of what they give you. You'll stay until the very end, until either death or prison."

Adam, a DZ Mafia member awaiting trial for several murders, spoke to the BBC via Snapchat from prison. "People noticed my determination, my cold-bloodedness and, without wanting to, I climbed up the ladder," he says. He admits the killings were "quite shocking" but claims he has no regrets. "If I hadn't done all of this, there are other people who would have done that in my place. I am just another brick in the wall."

The Social Media Recruitment Drive

Gangs are increasingly using social media to recruit, especially since the Covid pandemic pushed many drug sales online. Countless posts advertise jobs in Marseille for drivers, couriers, and hitmen, often with glamorized AI-generated images. These ads reach teenagers across France, from Paris to Nantes and Lille, drawing them to Marseille's Quartier Nord.

Law enforcement officials note that recruits often have no criminal past but have exploitable vulnerabilities, such as a difficult family life. "These people are recruited by unscrupulous sponsors who send them into the lion's den," says Thibaut Fontaine, head of France's anti-organized-crime unit.

A Losing Battle?

Police have made progress, arresting about 1,000 individuals associated with DZ Mafia since 2024 and incarcerating 600. But the battle is becoming more arduous. Zoulas warns of a potential systemic breakdown of the criminal justice system, citing road accidents, family violence, depression, suicides, and over 700 overdoses each year.

For families like Karine's, the pain is immeasurable. The restaurant where Hugo claimed to work existed, but staff told Karine they had never employed him. The reason for his death almost certainly lies within Marseille's Quartier Nord, a place where children are recruited to kill, and where the cycle of violence seems unending.
