A man has been arrested on suspicion of murder after a mother of two died in a house fire in Derbyshire.
The body of Sarah Jane Dudley, 33, was found in the burnt out house on Highwood Avenue at Bargate, Belper, at around 0200 BST on Sunday.
The man was expected to be questioned on Monday after a joint investigation by police and the fire service.
Fire officers initially believed a faulty fridge may have been the seat of the fire.
Neighbours tried to rescue Ms Dudley, but could not get into the house because of the flames.
Her two children were not staying with her at the time.
Detective Superintendent John Briggs, of Derbyshire Police, said the exact
cause of the fire had not yet been fully established and investigations were continuing.
