A woman has been arrested on suspicion of manslaughter following the death of a newborn baby in Wiltshire.
Emergency services were called to an address in Grange Park, Swindon, in the early hours of Monday morning, Wiltshire Police said.
A woman in her 30s was arrested on suspicion of manslaughter, but despite this the force said the death of the child was still being treated as unexplained.
A post-mortem is due to take place on Monday, and the suspect is currently being held in police custody.
Detective Inspector Simon Childe said: “This is a complex investigation into the very tragic death of a newborn baby.
“At this very early stage, although we have made an arrest, we are treating the death as unexplained and await the results of a post mortem examination next week.”
