Arrested by Dutch police at his farmhouse at Abcoude, he and his three alleged partners were tried at Utrecht High Court and accused of smuggling cannabis, ecstasy and cocaine. Douglas was also scheduled to be tried in Scotland, the Crown Office in Edinburgh filing for extradition only hours of his arrest. With testimony by agents from the Netherlands, Denmark, Spain and the United States, the prosecution accused Douglas and the others of earning 100 million from drug trafficking operations during the last three years. Douglas was eventually sentenced to four years imprisonment and fined 250,000 on 29 March 1994.
