Dozens of firefighters from all over Fife helped tackle a huge fire at a Kirkcaldy scrapyard on Tuesday night.
And police are appealing for witnesses as they confirmed it is being treated as suspicious.
Eight appliances from Kirkcaldy, Burntisland, Methil, Glenrothes and Dunfermline, alongside a water platform from Central region were involved in the blaze which was reported around 10.30 p.m.
When they arrived on the scene at Denburn Road, Kirkcaldy firefighters were confronted with several pockets of fire spreading rapidly around the site of Noble’s scrap merchants on Smeaton Industrial Estate, and they immediately called for backup.
Due to the heavy smoke the firefighters had to wear breathing apparatus, and both main jets and hosereel jets were used in extinguishing the flames.
Firefighters were on the scene all night bringing the fire under control, and did not leave the yard until around 8.30 a.m. on Wednesday morning.
Nearby residents reported hearing several loud bangs as petrol tanks of the vehicles exploded.
Detective inspector Colin Robson said: “This was a large-scale fire that has caused substantial damage. Thankfully no one has been injured as a result of the incident. We are appealing to the public for any information and are particularly keen to trace any vehicles which they may have seen in the area around the time of the fire.
“Extra police patrols of the area are now being carried out as part of our efforts to reassure the public and bring the culprits to justice.”
Anyone who has any information is asked to contact Police Scotland immediately on 101 or through Crimestoppers on 0800 555 111.
A joint investigation into the cause of the fire is being carried out between the fire service and Police Scotland.
