Thieves are believed to have broken into a Mid Wales building site over the weekend and stole keys to a machine worth £60,000.

Builth Building Services have appealed for any information about the theft which is thought to have happened sometime between Friday evening, December 7, and Monday morning, December 10 in Beulah, near Builth Wells.

It is believed that the intruders broke into the Beulah Road site through adjoining fields and took a set of keys for a Manitou Telehandler and cash from an on-site welfare facility.

They then unlocked the forklift machine and stole a Makita site radio.

A set of keys to a Monitou Telehandler (left) and a Makita site radio similar to the one pictured on the right were stolen.

Another set of keys was taken from a locking shed which stores items worth thousands of pounds.

Owner Guy Walker said the business has been running for 40 years and has not experienced a problem like it before.

"It's unfortunate," he said.

"We're putting up signs and CCTV, and we've changed the locks as a result. If they managed to start the machinery or something, it could have led to dreadful consequences and we wouldn't know about it until it was too late on Monday morning.

"A building site is not a play area," Mr Walker added.

Anyone who saw suspicious activity at the site over the weekend or has any information are urged to contact Mr Walker on 07980 603 043.
