A man's death is being treated as unexplained after he was found dead following a caravan fire.
The victim, a man in his 60s, was found after detectives and firefighters were called to a field alongside the A4095 in Oxfordshire after the caravan was spotted ablaze.
Firefighters found the man's body and carried it outside.
Police say they are treating the death as "unexplained" and are "keeping an open mind" as they continue their investigation.
They have appealed to anyone who may have seen something to come forward.
They added they are particularly keen to speak to the driver of a white flatbed truck towing a horse box.
"The man's death is currently being treated as unexplained, and although there currently does not appear to be any suspicious circumstances, we will be keeping an open mind as to the cause while the investigation continues."
A spokesman for Thames Valley Police said last night: "We are appealing for witnesses after a fire in a caravan in Witney in which a man tragically died.
"Officers were called, along with Oxfordshire Fire & Rescue Service, to reports of a fire just off the A4095 Woodstock Road, Witney.
"Tragically, a man who was in the caravan has died of his injuries at the scene."
Detective Inspector Pete Scott said: "Very sadly, as a result of this fire, a man aged in his 60s has passed away. Formal identification has not yet taken place, and work is ongoing to notify the next of kin.
"An investigation is continuing in order to establish the cause of the fire and there have been road closures in the area while this investigation has been conducted.
"I would appeal to anybody who was in the area and may have witnessed this to please get in touch with Thames Valley Police, either by reporting online or by calling 101.
"We would be particularly keen to hear from any drivers who may have passed the bus stop close to the Harvest Way junction with the A4095 between 2.45pm and 4.30pm to please check their dash-cam, and also anybody who may have been walking in fields adjacent to the A4095 between the same times.
"I would also appeal to potential witnesses who we believe were standing near the entrance of the farm on Woodstock Road who were observing fire crews. There were several adults and a number of children with scooters.
"I would also appeal directly to the driver of a white flatbed truck towing a horse box, which stopped on the road opposite the farm.
"The man's death is currently being treated as unexplained, and although there currently does not appear to be any suspicious circumstances, we will be keeping an open mind as to the cause while the investigation continues."
