Drugs with an estimated street value of more than £1million have been seized from flats above a Powys town centre bank this morning (Thursday, April 4).

A police warrant was carried out at the property above the Llandrindod Wells HSBC branch in Middleton Street where around 1,200 cannabis plants were found.

Following the discovery of the cannabis plants, two people were arrested and are currently in police custody with an investigation ongoing.

It is understood that the cannabis plants had been grown on three floors of the Middleton Street property for a number of months.

Dyfed-Powys Police officers raided the flats above the HSBC branch at around 10am on Thursday morning after acting on information about drugs or drugs supply in the town.

This is the latest crackdown on cannabis farms hidden in empty town centre buildings following raids at the former County Times office and ex-HSBC branch in Welshpool's Broad Street, and at a property on the Buttington Farm Industrial Estate on the outskirts of the town earlier this year.

Asylum seeker Dino Marku who had only recently entered Britain from Albania agreed to be a 'gardener' at the former County Times office after he was promised £10,000. He was jailed for 18 months in early March.

This is a developing story. We will continue to bring updates as and when we get them.
