Police investigating the death of a woman found dead in a burnt out caravan have been given permission to keep a 38-year-old man in custody.

The man, from the Wisbech area, was arrested on Sunday on suspicion of murder and grievous bodily harm after fire fighters discovered the body of the woman in a caravan blaze at Fen traveller's site Turf Fen Bridge, Murow, near Wisbech, on Saturday morning.

The caravan, which is close to a road, was almost completely destroyed by the fire. Yesterday part of the site was still cordoned off, as police and fire investigators examined the scene.

A 47-year-old woman, also from the Wisbech area, who was arrested on suspicion of perverting the course of justice, has been bailed until June 19.

A man taken to the Queen Elizabeth Hospital in King's Lynn suffering from smoke inhalation from the blaze has been transferred to Addenbrookes Hospital, near Cambridge, where police said he was still in a critical but stable condition yesterday.

An extension was granted to police to keep the man in custody longer by magistrates at Peterborough.

The dead woman and injured man have not yet been named and other details such as their ages have not yet been revealed.

Earlier police said the woman's death was “unexplained” and a post mortem examination would be carried out to ascertain how she died.

Officers are appealing for anyone who saw anything suspicious in the area to contact them.

Anyone with information should call 0845 456 4564.
