Operation Comby: 49 Arrests as UK Cracks Down on Cross-Border People Smuggling Networks
A major three-day enforcement operation targeting criminal networks that exploit the Common Travel Area to smuggle people from the Republic of Ireland into the United Kingdom has resulted in 49 arrests, with significant activity centred on Northern Ireland's ports and airports, UK Immigration Enforcement confirmed on Tuesday.
Background
The Common Travel Area — the arrangement that allows citizens of Ireland and the United Kingdom to move freely between the two countries without passport checks — has long been a feature of the relationship between the two islands. For the vast majority of travellers, it is an unremarkable convenience. But for criminal networks engaged in people smuggling, the CTA has historically represented an opportunity: a route into the UK that bypasses the more heavily monitored entry points at major English airports and seaports.
The route typically works by moving individuals — often migrants who have entered Ireland legally or irregularly — northward across the land border into Northern Ireland, and then onward to Great Britain via ferry or air. Because the land border between the Republic and Northern Ireland is open and unmonitored, the first point at which UK immigration authorities can intervene is at Northern Ireland's ports and airports, or at ports in Scotland, Wales, and England where ferries from Belfast and Larne arrive.
UK Immigration Enforcement has been running Operation Gull — a standing deployment at Northern Irish ports and airports — for several years, and the results have been significant. In the year to June 2026, Operation Gull resulted in nearly 1,000 arrests. Operation Comby, which ran from 22 to 24 September 2026, was a targeted intensification of that effort, involving coordinated patrols across multiple jurisdictions simultaneously.
Key Developments
The three-day operation involved patrols of ports, roads, and rail networks across Northern Ireland, Scotland, England, and Wales. The 49 arrests included individuals suspected of being in the UK without permission, as well as suspected facilitators of people smuggling networks.
Among the notable incidents, two Romanian women were arrested at Belfast International Airport after travelling from Ireland to Northern Ireland without the necessary permissions. Authorities identified them as potential victims of human trafficking and gathered intelligence on the criminal networks that had facilitated their journey — a reminder that people smuggling operations frequently exploit vulnerable individuals who are themselves victims rather than willing participants.
At Belfast Port, intelligence sharing between agencies led to the interception of a vehicle containing four Romanian nationals. During the search, officers discovered £130,000 worth of counterfeit Apple products, leading to the arrest of all four individuals, who now face removal from the UK. The discovery of the counterfeit goods alongside the immigration offences suggests the involvement of organised criminal networks with multiple revenue streams.
Minister for Border Security and Asylum Anna Turley said the government was prioritising the disruption of criminal gangs that exploit vulnerable people through deception, and confirmed that the Home Secretary had committed to doubling the Immigration Enforcement budget by the 2028/29 financial year.
Why It Matters
The scale and coordination of Operation Comby reflects a significant escalation in the UK government's approach to cross-border people smuggling. The 74 per cent surge in organised immigration crime arrests cited by the Home Office suggests that enforcement activity is intensifying across the board, not just in Northern Ireland. For the island of Ireland, the operation raises complex questions about the relationship between open-border arrangements and immigration enforcement. The CTA was designed to facilitate the free movement of Irish and British citizens — not to create a backdoor into the UK for irregular migrants. Maintaining the integrity of the CTA while preventing its exploitation by criminal networks is a delicate balance that requires close cooperation between Irish and UK authorities.
The PSNI's role in supporting UK Immigration Enforcement operations in Northern Ireland is also worth noting. Cross-agency cooperation of this kind — involving immigration officers, harbour police, and the PSNI — is essential to the effectiveness of operations like Comby, and reflects the increasingly joined-up approach to organised crime that has developed in Northern Ireland over the past decade.
Local Impact
The operation had a visible presence at Belfast International Airport and Belfast Port, the two main entry points for travellers moving between Northern Ireland and Great Britain. Passengers using these facilities during the three-day operation reported increased checks and a heightened enforcement presence. In Larne, where ferries to Cairnryan in Scotland depart regularly, similar activity was reported. The arrests at Belfast Port — and the discovery of counterfeit goods — will be of particular interest to the PSNI's organised crime unit, which has been tracking the activities of criminal networks operating across the Irish border for several years.
What's Next
UK Immigration Enforcement has indicated that Operation Comby-style intensifications will continue on a regular basis, supplementing the standing Operation Gull deployments at Northern Irish ports and airports. The Home Office has committed to increasing the Immigration Enforcement workforce by 60 per cent to support more frequent operations of this kind. Intelligence gathered during Operation Comby — including information about the networks that facilitated the movement of the individuals arrested — will be used to inform future enforcement activity. Several of those arrested face removal from the UK, while others are being assessed for potential victim-of-trafficking status.
