A woman has been arrested over a house fire which claimed the lives of two young children.
Niamh and Cayden Maynard, aged five and two, died at their home in the Fairfield area of Buxton, Derbyshire, on 23 April after they became trapped.
Their mother, Fiona Adams, 23, jumped to safety from a bedroom window on to a trampoline with her eight-month-old son Kiernan.
Derbyshire Police said a 23-year-old had been arrested over the incident.
A police spokeswoman said: “Police have arrested a 23-year-old woman in connection with a fatal house fire in Buxton in which two children died.
Fiona Adams escaped the fire and was treated for burns in hospital
“The woman, who is from the Fairfield area of Buxton, was arrested this evening. She will be interviewed by officers in due course.”
The spokeswoman said police were “keeping an open mind” about the cause of the fire.
Police have said they had been called to the address several times in the past three years, but these were mainly due to domestic matters.
The matter has been referred to the Independent Police Complaints Commission because officers went to the house on the evening of the fire after reports of a disturbance in the garden.
But Assistant Chief Constable Steve Cotterill said detectives had no information to indicate the family had been victims of a “dedicated campaign” of anti-social behaviour.
A 17-year-old youth arrested in connection with the fire was released on Sunday and ruled out as a suspect.
