The Herald today has the above and only this to explain it:

Two men have been arrested and charged in connection with a drugs recovery in Girvan.

Around 11am on Thursday, July 2, officers executed a warrant at a property in the town’s Dalrymple Street. Police said a cannabis cultivation was discovered within with an estimated street value of £300,000.

and:

That’s it. Might they have investigated who these men were and how they got to Girvan?

Could they be trafficked by a county lines gang from London or Birmingham?

Yes, it is highly plausible that Cam Vu Phung (30) and Nguyen Trung (32) could be victims of trafficking or modern slavery exploited by an organised crime group (OCG) operating in a manner similar to county lines gangs, potentially linked to networks from major cities like London or Birmingham. Their profile matches well-documented patterns across the UK, including Scotland. https://www.cam.ac.uk/research/news/cannabis-farms-are-a-modern-slavery-blind-spot-for-uk-police-study-suggests

Why This Fits Established Patterns

• Vietnamese nationals and cannabis cultivation: Vietnamese people (often young men) are disproportionately represented in UK cannabis farm cases and are frequently identified as victims of human trafficking and modern slavery. They are commonly smuggled or trafficked into the UK via dangerous routes (e.g., lorries through Europe), then forced into debt bondage to tend large-scale indoor cannabis grows. Threats of violence against them or their families back home keep them compliant. Many have no fixed abode, limited English, and are moved between properties by the gangs. https://www.antislavery.org/what-we-do/past-projects/trafficking-vietnam-to-uk/
• “No fixed abode” and the setup: This is a classic indicator in these cases. Victims are often housed on-site in the grow properties (sometimes locked in or isolated) with no independent accommodation or support network. The £300k Girvan farm on Dalrymple Street fits the typical low-profile, high-yield operation in a smaller town—ideal for OCGs expanding from urban hubs.
• County lines and OCG tactics: County lines gangs (often based in or operating from cities like London, Birmingham, Manchester, or Liverpool) specialise in exploiting vulnerable people—including migrants, those with addiction issues, or those with no fixed address—to produce, transport, and sell drugs in “county” (rural or provincial) areas. While county lines is most associated with heroin and crack cocaine distribution using runners, the broader serious organised crime model includes cannabis cultivation and the same exploitation methods (debt bondage, coercion, moving people around the UK). https://www.cps.gov.uk/prosecution-guidance/modern-slavery-and-human-trafficking-offences-and-defences-including-section
• Vietnamese-linked cannabis operations are often run by specific OCGs (sometimes intra-community), but there is overlap with wider UK drug networks. Gangs move victims and product between cities and outlying areas, and mixed networks or partnerships occur. Police and NCA operations have repeatedly uncovered Vietnamese victims being trafficked around the UK for cannabis farms.https://www.nationalcrimeagency.gov.uk/news/nca-targets-crime-group-suspected-of-operating-slave-labour-cannabis-farms
• Scotland context: Similar cases have occurred in Scotland (e.g., Paisley, East Kilbride, Dundee, Lochwinnoch), with Vietnamese individuals found in cannabis grows. There have been concerns from human rights groups about trafficked people (including children) being criminalised rather than supported as victims. Police Scotland actively targets county lines activity, which includes drug production and exploitation.https://www.theferret.scot/concerns-raised-over-trafficked-vietnamese/

Why doesn’t the Herald want to down that road, leading only to English cities?
