It's too much to handle on their own others have to be involved destination was UK so British-Irish most likely.
If it's this quantity of heroin destined for the Netherlands or the UK, then it's mostly Turkish or Turkish-Kurdish organized crime involved.
The strange thing in this case is the St. Willebrord connection; that's a bastion for traditional Dutch organized crime, not so much Turkish.
Traditional Dutch organized crime doesn't really traffic a lot of heroin far as I know; the Dutch mostly deal in large quantities of synthetic drugs, methamphetamines, cocaine, etc...
