Police are investigating an arson attack at a property in Keal Cotes, near Spilsby.
At around 9pm on Wednesday 1st October, the house on Main Road in the village was set alight and police believe this was done deliberately.
There were no occupants in the property at the time.
DC Emily Wooll-Rivers, from Skegness CID, would particularly like to trace the occupants of a dark green old shaped Vauxhall Corsa that was seen driving towards Spilsby at the time of the fire. It is thought there were three young males in the vehicle and they may be important witnesses.
Anyone with information should contact DC Wooll-Rivers by dialling 101 and quoting the incident number. Report crimes anonymously by contacting Crimestoppers on 0800 555 111.
