Wales (Wales Times) October 23, 2026 – ROCUs, police forces and border agencies supported a two-week national campaign against organised immigration crime, resulting in 452 arrests across the UK’s transport network.
Operation Lockstream was led by the Organised Immigration Crime Domestic Taskforce and ran between 21 September and 5 October 2026. According to the National Police Chiefs’ Council (NPCC), it involved 387 deployments and brought together 49 police forces and law enforcement agencies, including Police Scotland and the Police Service of Northern Ireland.
The operation targeted roads, railways and ports where intelligence suggested criminals were using transport networks to move people, commodities and assets across the UK. The NPCC said information shared between agencies helped officers identify and disrupt suspected organised immigration crime activity.
Regional Organised Crime Units (ROCUs) across England and Wales supported the campaign, alongside the Home Office, Border Force and Immigration Enforcement. The ROCU network said the two-week operation led to hundreds of arrests linked to organised immigration crime.
How many arrests were made?
The NPCC reported that 452 people were arrested during Operation Lockstream. It said 66% of those arrests were for immigration offences, while others were connected to offences identified during the wider enforcement activity.
As reported by the NPCC, Deputy Chief Constable Wendy Gunney, the council’s lead for serious organised crime and head of the Organised Immigration Crime Domestic Taskforce, said: “Arrests have been linked to illegal working, immigration offences and fraudulent documents, and we have gathered valuable information about the routes being used and why, the organised crime groups involved, and the tactics and methods being used.”
The national figures included activity by forces and agencies across the UK. Police Scotland separately reported 15 arrests connected to immigration offences at Loch Ryan and Cairnryan Ports, where officers engaged with 340 people during the operation.
What did police seize?
Officers seized 491 vehicles during the campaign, of which 79% were cars and vans. The NPCC also reported seizures of more than 17,000 cigarette packs, 40kg of cannabis with an estimated street value of more than £100,000, 22 weapons, 57 mobile phones and more than £600,000 in cash.
More than 900 police fines were issued during the operation, equivalent to more than £141,000. The NPCC said the campaign involved more than 6,000 vehicle stops and engagement with more than 11,000 people.
The seizures were not limited to immigration-related items. In Kent, KentOnline reported that officers recovered cannabis, cash, cocaine deals, mobile phones, illicit imported tobacco and weapons during separate stops connected to the wider operation.
Which regions took part?
Yorkshire and the Humber
The Yorkshire and Humber Regional Organised Crime Unit led activity across the regional motorway network and Humberside port area. As reported by Yahoo News UK, West Yorkshire Police said 645 vehicles were searched and 412 people were spoken to during 17 multi-agency deployments.
The regional operation resulted in six arrests connected to organised immigration, fraud and other offences. Officers seized 10 cars and 16 e-bikes, while 62 traffic offence fines worth £8,550 were issued. Police said the activity generated 63 intelligence reports, including 53 directly related to organised immigration threats.
Detective Chief Inspector Jim Horsfield of YHROCU said organised immigration crime was a complex and evolving threat and had been recognised in the UK as a national high-priority threat.
Greater Manchester
In Greater Manchester, the operation focused on Whitefield and Cheetham Hill between 21 September and 5 October. As reported by Bury Times, 22 people were arrested, 20 vehicles were seized and 26 traffic offence reports were recorded after 138 vehicles were stopped.
The report said officers from Greater Manchester Police’s Transport Policing and Crime Command worked with the Merseyside Matrix team, a Regional Organised Crime Unit and the Organised Immigration Crime Domestic Taskforce. Officers used intelligence and Automatic Number Plate Recognition technology to identify and intercept vehicles linked to suspected criminal activity.
Among the arrests was a suspected money launderer believed to be linked to around £100,000. Police also recovered approximately 30kg of cannabis, leading to an arrest on suspicion of drug supply, and detained a wanted robbery suspect.
Police Sergeant Neil Dalley, from GMP’s Roads Policing Unit, said: “The results of this operation demonstrate the value of intelligence-led policing and the strength of our partnership working.”
Kent
KentOnline reported that 22 people were arrested in Kent between 21 September and 7 October as officers targeted gangs suspected of transporting people, money and illegal goods across borders.
The operation included joint activity with Essex Police and the Metropolitan Police at the Dartford Crossing. KentOnline reported that six men were arrested on suspicion of drug dealing after a vehicle arriving from abroad was stopped and cannabis and cash were seized.
Further arrests included five Romanian men detained in connection with a burglary, a man wanted on a European Arrest Warrant for large-scale smuggling offences in Romania, and a Polish man arrested on the M20 after cocaine, cash and mobile phones were seized.
KentOnline also reported checks on fast-food delivery drivers in Tonbridge and Tunbridge Wells, and activity near Aylesford where officers recovered illicit imported tobacco worth about £5,000 and £2,000 in cash. The report said closure orders were being sought against some premises linked to illicit items and repeated immigration offences.
Scotland
Police Scotland said its activity at Loch Ryan and Cairnryan Ports led to 15 arrests for immigration offences. Those arrested were aged between 20 and 54.
The force said a 55-year-old man was arrested in connection with facilitating immigration and referred to partner agencies. Officers also issued four police warnings for drug offences and detected 11 road policing offences.
A 36-year-old man was arrested and charged in connection with drug offences after officers recovered drugs with an estimated value of £950, along with cash and an offensive weapon. Police Scotland said he was due to appear at Stranraer Sheriff Court on Monday, 5 October 2026.
Why did police target transport networks?
The NPCC said shared intelligence indicated that organised crime groups were exploiting roads, rail and ports to transport people, commodities and assets within the UK. The operation was designed to disrupt that activity beyond the immediate border.
Deputy Chief Constable Gunney said:
“Organised immigration crime does not begin and end at our borders. We know through shared intelligence that our roads, rail and port networks are being exploited by criminals as they transport people and goods across the UK.”
She added that police forces were working with partners to strengthen the response and that the results showed the impact of targeting and disrupting criminals.
What did the government say?
Border Security and Asylum Minister Anna Turley said criminal gangs exploiting roads, railways and ports should be “in no doubt” that authorities were pursuing them.
As reported by the NPCC, Turley said: “This coordinated response forms part of the largest crackdown on people-smuggling gangs on record. Enforcement action has delivered more than 6,500 disruptions to smuggling activity including arrests, convictions and seizures since the election.”
The National Crime Agency separately describes organised immigration crime as a threat that generates money for criminal groups, funds other forms of organised crime and can endanger migrants’ lives.
Background of the development
Operation Lockstream formed part of a wider national response to organised immigration crime, which includes illegal entry, people smuggling, illegal working, fraudulent documentation and the movement of criminal proceeds. The Organised Immigration Crime Domestic Taskforce coordinated the campaign, with ROCUs and local forces carrying out regional enforcement across transport routes.
The National Crime Agency says it is currently running more than 800 operations into serious and organised crime groups affecting the UK, and that its wider work has resulted in more than 12,500 arrests. The agency also states that organised immigration crime can fund other criminal activity and often places migrants at risk.
The latest campaign followed separate NCA and Border Force action earlier in October, when 25 inflatable boats destined to be shipped to cross-Channel people smugglers were seized at East Midlands Airport.
Prediction: What could this mean for businesses and communities?
For hauliers, delivery firms, logistics operators and businesses employing workers in transport-sensitive sectors, the operation signals continued enforcement around road, rail and port networks. Employers may face greater scrutiny of right-to-work checks, vehicle documentation and supply-chain compliance, particularly where staff work as drivers or delivery riders.
For local communities, the increased police presence and vehicle stops may lead to more visible road policing and further arrests connected to unrelated offences, as seen in Greater Manchester, Kent and Scotland. The NPCC said intelligence gathered during Lockstream would be used to refocus future enforcement and protect communities and legitimate businesses.
For people at risk of exploitation, the stated aim of the operation includes safeguarding vulnerable individuals. Police Scotland said a key purpose of its activity was to protect people at risk of exploitation, while working with agencies including HM Revenue and Customs, the Intellectual Property Office and the Scottish Environmental Protection Agency.
