Officers questioned 340 people at the Dumfries and Galloway ports, which run Stena Line sailings to Belfast and P&O crossings to Larne. Those held were aged between 20 and 54. A 55-year-old man was also arrested on suspicion of facilitating illegal immigration. A 36-year-old faced charges after police recovered £950 of drugs, cash, and an offensive weapon.

Nationwide, Operation Lockstream made 452 arrests, 267 of them for immigration offences.

Police seized 491 vehicles and over £600,000 in cash across the UK.
