DETECTIVES are tonight appealing for information after a high-value piece of machinery was deliberately set on fire within Dumbuck Quarry, Dumbarton, on Sunday.

Police and emergency services were called to the scene around 5.55pm where a heavy duty piece of plant equipment was discovered alight at the back of the quarry.

Following a joint investigation between police and fire services the incident is being treated as wilful.

Enquiries are underway to establish the circumstances surrounding the incident.

Detective Sergeant Gerald Shovlin from Clydebank CID said: “A very expensive piece of machinery, worth more than £250,000, has been destroyed as a result of this reckless act and it is vital that we trace whoever is responsible.

“There are several hill tracks that look down over the quarry and I would appeal to anyone who may have been walking in the area on Sunday evening to please get in touch.
