A goose-shooting guide who brought hunting parties to Scotland was involved in cross-border traffic in heroin, funnelling the Class A drug into Fife.

Alan Croston regularly travelled from his home in Wigan, Lancashire, to look after clients, including a Pakistani government minister, seeking to shoot wildfowl in the Fife area.

However, Croston became the target for a police surveillance operation, code named Rumba, which snared heroin worth up to £200,000 on the streets, along with more than £25,000 cash.

Croston, 58 and his brother Anthony, 53, along with father and son Angus and Lee Robb, 59 and 29, and thermal engineer Lee Griffin, 44, were convicted of being concerned in the supply of the Class A drug, following a trial at the High Court in Edinburgh.

The judge, Lord Uist, ordered all should be held in custody ahead of sentencing next month and told them to expect lengthy prison sentences.
