A police investigation is underway following a spate of wilful fire-raisings in Alexandria, West Dunbartonshire.

A primary school, new build properties at a construction site and three cars were all targeted in the attacks.

Officers are investigating the incidents which took place between Monday, June 19, and Thursday, June 22.

The first incident occurred at around 2am on Monday when wheelie bins outside a house in India Street were set on fire followed by another arson attack on a construction site in Napierston Place when a new build property was targeted at around 3am.

A property on another construction site in Campbell Street was also set on fire a short time later and a car was deliberately set alight in Dalmonach Road at around 7am the same day.

Officers are also investigating a further two incidents when cars were set on fire in Thomas Street around 1am and in Glebe Gardens two hours later on Wednesday, June 21.

St Mary's primary school in Bank Street, Alexandria, was targeted in the early hours of Thursday, June 22, but the fire did not take hold and was extinguished by the Fire Service.

Officers have been reviewing CCTV from in and around these areas and have also been carrying out door-to-door enquiries.

The locations have also been subjected to a forensic examination with items being removed for further analysis.

Police have moved to reassure locals in the area and say all scenarios are being looked at as they appeal for information.

Chief Inspector Donald Leitch, Area Commander for West Dunbartonshire said: "These incidents will no doubt be causing some concern to local people so I would like to reassure them that we are doing all we can to find whoever is responsible.

"Extensive enquiries are being undertaken by detectives with a number of lines of enquiry being considered. At this stage, we do not know if the incidents are linked, if they have been carried out by one person or if they are random but I can assure you all scenarios are being considered and will be followed up.

"I would like to appeal to people in the areas involved to think back and consider if they saw or heard anything suspicious or unusual.

"No matter how insignificant you think your information is, please pass it on to us and let us work out its relevance.

"I would also ask people to be vigilant and report any suspicious activity to police.

"Additional officers will be on patrol to provide reassurance for people and anyone with any concerns should speak to them."
