The drugs were recovered from a large detached house in Dalry, Ayrshire, and a flat in Bridgeton in Glasgow.

Police said the haul at Dalry, taken from two large cultivation sites constructed in the property, has a sale price of around £300,000, with a further 3kg of the drug found in the city raid.

Four men, two aged 20 and two aged 34, were arrested at the Dalry property. Three males – aged 39, 34 and 24 – were arrested in connection with the raid in Bridgeton.

The raids were part of Operation League, which targets the cultivation of cannabis by organised crime gangs from south- east Asia.
