Police have discovered more than 100 cannabis plants at a farm.
Officers from Dyfed-Powys Police were at the farm between Pontarddulais and Tycroes on unrelated matters when they noticed two polytunnels outside.
Upon closer inspection officers found a large cultivation of cannabis at various stages of growth growing inside the tunnels.
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.
Police are unable to give a precise location of the Carmarthenshire farm but have said that it was between the town of Pontarddulais and the village of Tycroes, outside Ammanford.
Officers have remained at the property to dismantle the cultivation and seize the plants for destruction.
Sergeant Gemma Davies for Dyfed-Powys Police 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.”
