Drugs worth more than £180,000 have been recovered as part of a multi-agency operation targeting organised immigration crime across Scotland, including activity at Glasgow Airport in Paisley.
Police Scotland officers took part in the three-day operation alongside national law enforcement partners. The activity began on Tuesday, 24th February 2026 and focused on transport hubs including airports, roads and ferry terminals.
At Glasgow, Aberdeen and Edinburgh airports, officers met a total of 78 flights as part of the operation.
Across the wider operation, officers engaged with more than 660 people travelling in and out of Scotland.
At ferry ports in Stranraer, 30 vehicles were searched. This led to the discovery of 27 kilograms of cannabis at Loch Ryan.
In total, drugs worth around £180,000 were recovered. Officers also seized £7,000 in cash.
Four people were arrested in connection with drugs, road traffic and immigration offences.
The activity formed part of Operation Lockstream, which aims to tackle organised immigration crime and protect vulnerable people who may be at risk of exploitation.
Police Scotland worked with partners including the National Police Chiefs’ Council, Border Force, Home Office Immigration, His Majesty’s Revenue and Customs and the Scottish SPCA.
Assistant Chief Constable Stuart Houston, Police Scotland’s lead for Organised Crime and Counter Terrorism, said: “Organised immigration crime is happening now in Scotland and tackling it is a priority.
“We know that criminals use our transport hubs for a range of illegal activities, and working closely with our partners, we remain focused on targeting those who exploit vulnerable people solely for financial gain.
“Action like this is only possible through the continued support of our communities. Anyone with information or concerns should contact Police Scotland on 101 or make a call anonymously to Crimestoppers on 0800 555 111.
“I can assure you that you will be listened to and the information you provide could prove vital in helping us identify those involved in this type of criminality.”
Deputy Chief Constable Wendy Gunney, the National Police Chiefs’ Council’s Organised Immigration Crime Domestic Taskforce lead, said: “This week we have leveraged all of law enforcement powers at the UK’s borders to target people who come to the UK to commit any form of criminality.
“It has been a significant joint effort involving many officers, staff, and multiple agencies, across the rail network, roads, seaports and airports.
“This activity has generated strong results and crucial intelligence that will help us recognise patterns and better understand these criminal networks, ensuring we collectively continue to identify offenders and bring them to justice.”
