Underground Cannabis Farm Discovered Near Kustendil, Bulgaria: A ‘Subterranean City’ of Narcotics
Kustendil, Bulgaria – Authorities in Bulgaria have uncovered a large-scale, sophisticated cannabis cultivation operation hidden within a former lead and zinc mine near the village of Garliano, in the Kustendil province. Described by the Ministry of Interior (MVR) as a “subterranean city,” the operation involved over 20 interconnected chambers repurposed for the illegal growing of marijuana. The discovery highlights the increasing sophistication of drug trafficking networks operating within the region and raises questions about the ownership and oversight of abandoned industrial sites.

The raid, conducted in recent days, yielded over 67 kilograms of marijuana, more than 600 rounds of ammunition, and nearly €600,000 in cash, according to initial reports from the MVR. However, police officials now indicate the scale of production was significantly larger than initially assessed. The facility was well-equipped, suggesting a substantial investment and organized criminal activity. Three individuals have been arrested in connection with the operation, with a fourth suspect currently at large. One of those detained is under house arrest due to health concerns.
The investigation, a joint effort between the General Directorate for Combating Organized Crime (GDBOP) and the State Agency for National Security (DANS), revealed that the abandoned mine had been transformed into a complex network of growing rooms and living quarters. The mine, which had been privately owned, was reportedly adapted to provide optimal conditions for cannabis cultivation, utilizing advanced technology and infrastructure.
From Mine to ‘Narcotics City’: The Scope of the Operation
The operation’s location within a former lead and zinc mine, situated approximately one kilometer underground, presented significant logistical challenges for law enforcement. The extensive network of tunnels and chambers required a coordinated and thorough search. According to reports from bTV Novinite, the facility included not only cultivation areas but too rooms designed for habitation, indicating a prolonged and sustained operation. bTV Novinite reported that the individuals arrested have prior criminal records, including previous convictions for drug trafficking.
Authorities believe the cannabis produced was intended for trafficking, rather than local consumption. Emil Borisov, Deputy Head of GDBOP, stated that efforts are underway to identify the owner of the mine, a crucial step in dismantling the entire criminal network. The substantial amount of cash seized suggests a well-funded operation with established distribution channels. The presence of over 600 rounds of ammunition also indicates a potential for armed resistance and a willingness to use violence to protect the illicit enterprise.
The discovery comes amid growing concerns about the increasing prevalence of organized crime in Bulgaria and the country’s role as a transit route for illicit drugs. The sophisticated nature of this operation suggests a level of planning and resources that points to a well-established criminal organization.
Legal Ramifications and Ongoing Investigation
The three arrested individuals face charges related to drug trafficking, money laundering, and illegal possession of firearms. Prosecutors have indicated they are building a comprehensive case to ensure those responsible are brought to justice. Novini Sega reports that authorities are currently working to trace the financial flows associated with the operation, aiming to identify and seize any additional assets linked to the criminal enterprise.
The investigation is focusing on identifying the mine’s owner and any potential accomplices who may have been involved in facilitating the operation. Authorities are also examining the possibility that the mine was specifically acquired for the purpose of establishing the cannabis farm, or whether the criminal organization exploited an existing abandoned site. The scale of the operation suggests a significant period of preparation and investment, raising questions about how it remained undetected for so long.
The Challenge of Abandoned Industrial Sites
This case highlights a broader issue concerning the security of abandoned industrial sites across Bulgaria. Many former mines and factories are left unattended, creating potential havens for criminal activity. The lack of adequate security measures and oversight makes these sites vulnerable to exploitation by organized crime groups. The Bulgarian government is facing increasing pressure to address this issue and implement stricter regulations regarding the management and security of abandoned industrial properties.

The discovery of this “subterranean city” of narcotics underscores the require for enhanced law enforcement efforts and international cooperation to combat drug trafficking and organized crime. The case serves as a stark reminder of the challenges faced by authorities in tackling the evolving tactics of criminal networks and the importance of proactive measures to prevent the exploitation of vulnerable infrastructure.
What Happens Next?
The investigation remains ongoing, with authorities continuing to gather evidence and pursue leads. The focus will be on identifying the mine owner and any other individuals involved in the operation. Prosecutors are expected to present their case in court in the coming months, seeking convictions and substantial penalties for those found guilty. The Bulgarian government is also likely to review its policies regarding the security of abandoned industrial sites, potentially implementing stricter regulations and increased surveillance. Further updates on the case are expected as the investigation progresses.
This incident serves as a critical reminder of the persistent threat posed by organized crime and the importance of vigilance in safeguarding national security. The successful dismantling of this sophisticated operation represents a significant victory for Bulgarian law enforcement, but the fight against drug trafficking and criminal networks remains a continuous and evolving challenge.
