A man has been arrested on suspicion of murder after a woman and three children died after a house fire in Bradford. Police were called in the early hours of Wednesday by the fire service, who had attended the blaze in a property in Westbury Road. Detectives from West Yorkshire police said initial inquiries suggested that the fire had been started deliberately. A 29-year-old woman was pronounced dead at the scene, while three children – two girls, aged nine and one, and a five-year-old boy – were taken to hospital. All three children later died from the injuries they sustained in the fire. A 39-year-old man was arrested at the scene on suspicion of murder and taken to hospital with critical injuries. He remained in hospital with serious injuries caused by the fire, police said. DCI Stacey Atkinson, of the homicide and major inquiry team at West Yorkshire police, said: “This is an absolutely devastating incident in which three children and a woman have lost their lives. Our thoughts remain with their family, friends and loved ones. “Early inquiries show that the fire was started deliberately, and we have arrested one man on suspicion of murder. He is seriously ill in hospital today as a result of injuries caused by the fire.” She added: “We are appealing to anyone who was in the area at the time of the incident or who has CCTV or doorbell footage to come forward. “Specially trained officers are supporting the family, and we are working with local neighbourhood officers to carry out inquiries and provide reassurance in the area.” Anyone who witnessed anything suspicious is asked to contact police via 101.
