The death of a woman, whose body was discovered by a road in Frithville, Lincolnshire, is being investigated.
The body, of a woman aged in her late-thirties to mid-forties, was found on Saturday on land off Westville Road.
Police said they had not been able to identify the woman, who was wearing a white T-shirt with a blue star on it, blue tracksuit bottoms and flip-flops.
A post-mortem examination did not determine the cause of death but it is not thought to be suspicious.
Police are now awaiting toxicology reports.
They have appealed for anyone who may have seen the woman in the area, or may know who she is, to contact them.
She is described as 5ft 2in, of medium build and with light brown shoulder length hair.
