A council-owned plant nursery, including a large greenhouse, has been severely damaged by a fire in Dumbarton.

Police are treating the fire as deliberate, describing the incident as an act of "mindless vandalism".

At around 1.30am on Saturday, fire crews were called to the scene at the Levengrove Depot, owned by West Dunbartonshire Council.

A fire had developed within the plant nursery, including a large poly-greenhouse structure used to grow plants for planting in the local area.

The fire was extinguished and no one was injured during the incident, but the cost of the damage is still being worked out.

Detective constable Andrew Fearnside, Clydebank CID, said: "This was a senseless act which has severely damaged a plant nursery owned by the West Dunbartonshire Council.

"Although no plants were damaged, this is an area used to grow plants and make the local area a greener place to live, work and visit.

"As a community, this type of mindless vandalism will not be tolerated. Our enquiries are underway to trace the person responsible and ensure they are held to account for their actions.

"The area is popular with local dog walkers and offers shortcuts through the main park area. It may be that you witnessed the fire, or perhaps seen someone acting suspiciously in the early hours of Saturday morning.

"Any information, no matter how small, will greatly assist our ongoing investigation."

Anyone with any information that will assist police with the investigation can contact Clydebank CID via 101, or alternatively information can also be passed in confidence to Crimestoppers on 0800 555 111.
