Police have seized 100 cannabis plants after finding a large cultivation on a farm in Wales in recent days.

Dyfed-Powys Police officers attended the farm, between Pontarddulais and Tycroes in Carmarthenshire, on an unrelated matter on Tuesday (September 15).

While at the property, they came across the plants growing in two polytunnels.

Sergeant Gemma Davies said: "Our officers were providing support to partner agencies at the property when they noticed two polytunnels on the land.

They looked inside and found 100 cannabis plants in various stages of growth.

"While our officers were not at the farm in relation to concerns over cannabis, this discovery shows the vigilance shown in their surroundings, which resulted in the disruption of a large cultivation."

Officers remained at the farm to dismantle the cultivation and seize the plants for destruction.

A 32-year-old man was arrested on suspicion of producing a controlled drug of class B. He has been released under investigation while further enquiries are carried out.

Cannabis operation discovered in bunkers

Meanwhile, more than £500,000 (€549,480) worth of cannabis was discovered in underground bunkers which were accessed within farm sheds in the English county of Lincolnshire, local police confirmed.

A pre-planned warrant at a Lincolnshire farm led to searches taking place over nine days following the discovery of the bunkers.
