Officers are appealing for information following a fire at a block of flats in Cardenden that they say was deliberate.
No one was injured in the incident on Cardenden Road on Tuesday evening (15 August, 2023), but significant damage was caused.
Police and emergency services were called and the fire was extinguished by Scottish Fire and Rescue Service.
A number of properties had to be evacuated.
Police say they have made extensive enquiries and are keen to trace a man seen in the area around the time of the incident.
He is described as being of average height, stocky build, wearing dark clothing, possibly wearing a grey jacket with a hood up and white or light coloured trainers.
Detective Inspector Kieran Marsh, of West Fife CID, said: “This could have had catastrophic consequences for people, including young children, who should have been safe in their homes.
“I would urge anyone with any information to make contact with police.
“Think back, did you see or hear anything suspicious or unusual in the area between 11pm on Tuesday, 15 August, and 2am on Wednesday, 16 August? Perhaps you have private CCTV or dash-cam footage that could assist with our enquiries? If so, please get in touch.”
