Portugal seizes 5 tonnes of cocaine on container ship off Lisbon; one detainee found dead in cell

The interception

In the early hours of Tuesday, Portuguese military personnel rappelled from a helicopter onto a Hong Kong-flagged container ship in the Atlantic, roughly 1,185 kilometres (640 nautical miles) off Lisbon. The vessel had departed from Panama and was heading towards northern Morocco. Intelligence shared through the Maritime Analysis and Operations Centre – Drugs (MAOC-N) had pinpointed the location of the hidden cargo, allowing the boarding teams to move directly to the right section of the ship.

It was a large operation. The result was achieved in a short space of time, but it required a huge mobilisation and coordination of human and logistical resources.

The Air Force logged 32 flight hours, including nine hours of transport, 16 hours of long-range reconnaissance, and 17 hours of helicopter infiltration. The Navy deployed 130 personnel who accumulated more than 85 operational hours. Once secured, the ship was escorted to the port of Sines, where it docked early the same morning.

Cargo and crew

Inside the vessel, authorities found approximately five tonnes of cocaine. The Judicial Police believe the drugs were not loaded at the port of origin but were transferred at sea during the voyage, a common tactic. Two foreign nationals travelling clandestinely on board were arrested, along with one crew member suspected of aiding them. The stowaways were tasked with guarding the shipment and ensuring its later removal.

The drugs were brought on board during the journey, in an operation carried out by the traffickers on the high seas.

The detainees were identified as an Italian, a Colombian, and an Indian national. The container ship, measuring 265 metres, was allowed to leave Sines on Wednesday morning and resumed its course towards Morocco.

Death in custody

On Wednesday morning, around 08:00, prison guards opening the cells at the Lisbon prison annex next to the Judicial Police headquarters found one of the three detainees dead. The Directorate-General for Reintegration and Prison Services (DGRSP) confirmed the man had been held alone in an individual cell and was discovered hanged. Emergency services were called immediately but pronounced him dead at the scene.

A detainee, admitted with a committal order following the arrests of Operation SkyDrop, was found lifeless in the cell he occupied alone at the prison facility next to the Judicial Police in Lisbon.

A source close to the case told the Lusa news agency that the deceased was the Indian crew member who had been searched at the port of Sines. The DGRSP opened an internal inquiry into the circumstances of the death. The other two detainees were brought before a court later that day for their first hearing.

International cooperation

The operation, codenamed Skydrop, was built on intelligence exchanged between Portugal, Spain, and the United Kingdom. David Ferré, a representative of the Spanish National Police, stressed that the rapid sharing of information allowed the authorities to mobilise resources and intercept the vessel far from shore.

The moment we obtained the information and shared it, we mobilised those resources and means to carry out a boarding at so many nautical miles and successfully complete an operation like this – that is the real example of international cooperation.

The Judicial Police said the investigation, which began in early August, is still examining whether the shipment belonged to a South American organised crime group. All possibilities remain open, according to investigators.

Record seizures

The five-tonne haul pushes Portugal’s cocaine seizures this year to 28 tonnes in the first eight months alone, already exceeding the total for all of 2025. João Oliveira attributed the rise partly to increased global production and trafficking, but also to improved enforcement capacity. He rejected the notion that Portugal is an easy entry point, while acknowledging that its geographic position on Atlantic routes makes it particularly exposed.
