Police are investigating the death of a one-month-old baby girl.
Detectives were called after the girl, from Plymstock, Plymouth, was admitted to the city's Derriford Hospital on Thursday night.
She was taken to the high-dependency unit, where she died earlier on Friday.
A Devon and Cornwall Police spokesman said: "Police continue to investigate the circumstances leading up to the death, but at the moment it is being treated as unexplained."
A post-mortem examination will be carried out early next week in a bid to establish what caused her death.
