Police say they are contacting the families of long-term missing people in the Glenrothes area - after human remains were found on an industrial estate in the town.
Officers were called to Whitehill Road at around 5.20pm yesterday.
They are now trying to confirm who the remains belong to - and a large police presence remains at the scene.
Detective Inspector Christopher Dow, the senior officer investigating the discovery, said: "A full investigation is underway to establish the person’s identity and the circumstances surrounding how they came to be there, as well as what may have happened. Inquiries are still at an early stage.
"We're contacting relatives of long-term missing people in the local area, and will continue to keep them updated during the investigation. Our thoughts are with them all at this difficult time."
One of those missing people is Allan Bryant, who was last seen leaving Styx nightclub in the town - just over a mile away - in November 2013.
No trace of him has ever been found.
