A GAMEKEEPER and a builder who ran a secret drugs ''factory'' within a forest were each jailed for six years yesterday.

William Stirrat, 44, and William Findlay, 37, were part of a gang running a ''highly organised'' drugs operation.

They were caught by police with 50 kilogrammes of amphetamine, estimated to be worth (pounds) 500,000, the High Court in Glasgow heard.

Police found the drugs being cut, weighed, and wrapped for distribution in two huts seven miles deep into the forest in the Douglas and Angus estates at Crawford, Lanarkshire, on March 4, 2002.

Both men appeared in court for sentence yesterday after previously being convicted by a jury after a four-week trial at Hamilton.

Stirrat was the gamekeeper at the estate and Findlay, of Baillie Drive, Cumnock, was part of the gang. They had denied dealing in the drug at Wedder Hill, Glentaggart, in the estate.

Jailing them, Lord Emslie said they had been involved in a ''highly organised'' drugs crime.

Two other men, Gary McKay, 37, of McClymont Court, and George Hollow, 34, of George McTurk Court, both Cumnock, Ayrshire, were found not guilty by the original jury.
