Cumali Ozgen: the cartel's onboard agent in Ireland's largest cocaine seizure

Cumali Ozgen was formally listed as a cook and cleaner on the MV Matthew. The Special Criminal Court found a different reality: the Dutch national was the Dubai-based crime group's agent aboard the ship and had the closest connection to the organisation directing the attempted delivery of 2.2 tonnes of cocaine.

Ozgen, also known as Jimmy, pleaded guilty to possessing cocaine for sale or supply aboard the MV Matthew between 24 and 26 September 2023. On 4 July 2025, the three-judge Special Criminal Court imposed a 20-year sentence, the longest of the eight terms arising from the operation.

The €157 million figure belongs to the entire 2.2-tonne shipment seized from the vessel. It is not a finding that Ozgen owned drugs worth that amount or would personally have received the proceeds. His individual responsibility rests on his guilty plea and the court's assessment of the role he performed for the organised crime group.

A false job description

Ozgen was formally presented as the ship's cook and cleaner, but he had no maritime experience and occupied the prestigious pilot's cabin. Evidence before the court showed him communicating regularly with a Dubai contact while the ship crossed the Atlantic. RTÉ reported that he contacted that person about every three days.

The court found that Ozgen was the criminal organisation's man aboard the vessel: its agent, and its eyes and ears. Ms Justice Melanie Greally said he had the closest connection to the Dubai-based group that planned and financed the operation and stood to benefit if it succeeded.

That finding placed him above the other defendants in culpability. The court did not describe him as belonging to the organisation's upper echelon, but it found that he was a trusted and committed component in an operation requiring specialised people to make international trafficking possible.

The Atlantic operation

The bulk carrier sailed from Curaçao, off Venezuela, and crossed the Atlantic. The cocaine was intended to be transferred at sea to a smaller vessel, the Castlemore, which had been bought in Castletownbere, Co Cork. That collection plan failed when the Castlemore ran aground off the Wexford coast and its two occupants had to be rescued.

As the Irish authorities closed in, the MV Matthew ignored five directions from the Naval Service vessel LÉ William Butler Yeats. The ship was manoeuvred in an attempt to frustrate the intervention, creating danger for the Army Ranger Wing members preparing to board from an Air Corps helicopter in rough conditions.

Evidence reported at sentencing connected Ozgen directly to the cargo. He admitted loading the cocaine crates and trying to burn them as the authorities pursued the ship. Army Rangers ultimately fast-roped onto the moving vessel on 26 September 2023. The joint operation involved the Garda National Drugs and Organised Crime Bureau, Revenue Customs, the Naval Service, Air Corps and Army Ranger Wing.

A network directed from Dubai

Investigators recovered communications that helped expose how the shipment was being managed. The court heard that the transnational group directing the operation from Dubai had immense capability, extensive resources and global reach. It had acquired two costly vessels and used Starlink communications, encrypted messaging and location-spoofing techniques.

Ozgen's role was not inferred merely from his presence on the ship. It was established through his guilty plea, the communications evidence, the court's assessment of his relationship with the organisers and his admitted handling of the cargo during the pursuit.

Reporting said Ozgen had been promised between €50,000 and €100,000 for participating but received nothing. That promised payment is separate from both the wholesale value of the seized shipment and the financial position of the organisation behind it.

From a 30-year headline to 20 years

The Special Criminal Court treated the attempted shipment as exceptional and egregious. It selected a 30-year headline sentence for Ozgen, the highest starting point among the eight defendants, before considering mitigation.

Ozgen had no previous convictions. The court took account of his guilty plea, personal and family circumstances, prison conduct, enhanced status for good behaviour, expressions of remorse and the additional difficulty of serving a long sentence in a foreign country. It reduced the term to 20 years and backdated it to his arrest in September 2023.

The absence of previous convictions was mitigating; it did not erase the scale or sophistication of the conduct admitted. Ozgen still received the longest final term in the case because the court placed him closest to the directing organisation.

Chronology

Public-cost benchmark

An Oireachtas written answer records the Irish Prison Service's 2024 average annual cost of an available staffed prison space as €99,072, excluding capital expenditure. Applied mechanically across a 20-year sentence, that gives a present-day benchmark-equivalent of €1,981,440.

This is not an invoice for Ozgen and it is not a prediction of the exact time he will spend in custody. Annual prison costs change, a system-wide average is not the marginal cost of one prisoner, and sentence administration may affect actual custody. The figure also excludes the substantial but unitemised cost of the international intelligence work, naval and air deployment, Army Ranger Wing boarding, Garda and customs investigation, prosecution, court proceedings and legal aid.

What the record establishes

Reliable court reports identify Ozgen as a Dutch national and as being from the Netherlands. They do not establish his birthplace, ethnic origin, date or method of entry into Ireland, residence permission, asylum history or exposure to deportation proceedings. This file makes none of those additional claims.

The adjudicated facts are already severe without embellishment: a guilty plea for possession of cocaine for sale or supply, a judicial finding that he was the directing cartel's onboard agent, and a 20-year sentence arising from the largest cocaine seizure in Irish history. This file records the sentence imposed. It does not claim an appeal outcome that the reviewed sources do not report.
