Sierra Leone’s Transnational Organised Crime Unit has moved to distance the country from what has become the single largest cocaine seizure in recorded maritime history, insisting that the cargo vessel MV Arconian departed Freetown’s port without any detected or declared narcotics consignment even as the full weight of an international criminal investigation closes in on the West African nation from multiple directions.
Speaking at a press conference in Freetown, TOCU Director CSP Michael J.K. Laggah stated that the vessel underwent full routine checks while docked in the capital and was cleared with legitimate cargo only, with no indication of concealed narcotics. All inspections, cargo documentation, CCTV footage, port movement logs, and loading records showed no evidence of narcotics concealment during the vessel’s stay in Sierra Leonean waters. Investigators confirmed that the ship officially departed carrying palm kernel cargo, marine diesel, and water supplies, with no reported security breach or suspicious maritime activity at the port.
Spain’s Guardia Civil intercepted the 91-metre cargo vessel Arconian on May 1, 2026, off the coast of Western Sahara, seizing an estimated 30 to 45 tonnes of cocaine in what is expected to be the largest drug bust in Spanish history. Spain’s Interior Minister Fernando Grande-Marlaska stated the seizure would rank among the largest both nationally and internationally.
On May 1, Spanish police intercepted the cargo ship and found 1,279 packages containing a total of 30,216 kilograms of cocaine on board. All 23 crewmembers aboard were detained; media reports indicate they are from the Philippines, the Netherlands, and Angola.
The vessel, which is 91 metres in length, is registered in Comoros and listed as owned by a company in Sierra Leone. It was reporting a destination of Benghazi, Libya, but authorities believe that information may have been false. Tracking data confirmed the Arconian departed Freetown, Sierra Leone, on April 22.
The most significant detail to emerge from TOCU’s press conference and the one that raises the most troubling questions about how the drugs came to be aboard is the crew discrepancy. The vessel reportedly sailed from Freetown with 17 crew members, but Spanish authorities later reported detaining 23 individuals on board during the interception. The discrepancy has raised questions over possible boarding activity after the ship left Sierra Leonean waters. TOCU further noted that the vessel’s extended voyage time longer than the expected transit duration suggests possible irregular movements outside national jurisdiction, reinforcing suspicions of offshore exploitation by transnational trafficking networks.
According to reporting based on confidential court documents, the motherlode of drugs was protected by six men with machine guns — five Dutch nationals and a Surinamese national. This armed security detail, absent from Freetown’s departure manifest, appears to constitute the six unaccounted persons TOCU has flagged in its preliminary findings. The implication is stark: the six armed guards, and possibly the cocaine itself, were transferred onto the vessel at sea after it cleared Sierra Leonean territorial waters a method increasingly favoured by sophisticated trafficking networks to frustrate port-side inspections.
The MV Arconian case cannot be examined in isolation from the presence of fugitive Dutch drug lord Jos Leijdekkers, known internationally as “Bolle Jos,” who has been sheltering in Sierra Leone for more than two years.
Dutch drug trafficker Jos Leijdekkers, alias “Bolle Jos,” allegedly moved to Sierra Leone in 2024, where he reportedly began a relationship with the daughter of President Julius Maada Bio. Bolle Jos was sentenced in absentia to 24 years in prison by a Dutch court for his role in drug trafficking operations and an attempted murder. He must also pay 96 million euros to the Dutch state for profits from drug trafficking. In Belgium, he has been sentenced in separate large-scale trials to a combined 50 years in prison.
Due to the enormous scale of the cocaine shipment, the Dutch suspects, and Sierra Leone as the departure point, sources within both the underworld and law enforcement told investigators that Bolle Jos Leijdekkers is considered the most likely suspect as the operation’s mastermind. The Spanish Interior Minister publicly linked the operation to the notorious Dutch-Moroccan “Mocro Mafia” criminal organisation, a network repeatedly associated by European investigators with Leijdekkers.
In a separate and parallel development, Bolle Jos was convicted just this week by a criminal court in Dendermonde, Belgium, and sentenced to eight years in prison for his role in a 2023 operation that smuggled 11 tonnes of cocaine from Sierra Leone into the Port of Antwerp, concealed in palm kernel meal a cargo strikingly similar to that declared on the Arconian’s official manifest.
Dutch special forces were reportedly ready to arrest Leijdekkers in Sierra Leone on at least two separate occasions, but the operations were called off at the last minute at the highest level. He remains in the country despite mounting international pressure. Sierra Leone has no extradition treaty with the Netherlands, making Leijdekkers’ capture and transfer deeply uncertain.
The interception of the Arconian has reignited domestic political debate in Sierra Leone. Leader of the Opposition wrote directly to President Julius Maada Bio, warning that over the last two years Sierra Leone has increasingly appeared in international criminal investigations, media reports, law enforcement briefings, and extradition proceedings concerning cocaine trafficking, organised crime syndicates, and transnational drug cartels a pattern he described as posing a serious threat to the country’s national image, diplomatic standing, internal security, and future economic prospects.
International analysts note that Sierra Leone is a major hub for cocaine shipped or flown to West Africa, where it is divided up and sent onward, mainly to Western Europe. A study published in March by the European Union found that traffickers have taken advantage of West Africa’s porous borders as well as high levels of corruption within port authorities, security services, and political structures.
Authorities also found 42,000 litres of gasoline aboard the Arconian intended to refuel go-fast boats that would have been used to unload the shipment on the Iberian Peninsula a logistical footprint indicating that the operation was planned to distribute cocaine across multiple small European ports simultaneously.
TOCU has confirmed that investigations remain ongoing and that the Government is pursuing diplomatic engagement with Spain to uncover the full circumstances surrounding the bust. Formal communication from Spanish authorities is still pending. TOCU also clarified that the ship is linked to a foreign-registered company not based in Sierra Leone, distancing local shipping entities from the alleged drug operation.
The Arconian’s registered owner is listed as Serenity Shipping SL Ltd, a company based in Freetown, Sierra Leone. El País reported that the company acquired the vessel on February 2, 2026.

For a country that presents itself to international partners as committed to fighting organised crime, the MV Arconian affair represents a defining moment. TOCU’s findings — that no cocaine left Sierra Leone’s shores on the vessel’s documented manifest may be accurate and verifiable. But the six extra gunmen, the convicted drug lord living under political protection in Freetown, the palm kernel cover story echoing a prior Antwerp operation, and the Colombian cocaine that somehow ended up on a ship that last touched land in Sierra Leone all demand answers that a single press conference cannot provide.
The Government’s credibility on this matter will ultimately rest not on what was declared at the port, but on whether Freetown cooperates fully and transparently with Madrid, Amsterdam, and Brussels as the full architecture of this transnational operation is dismantled.
