A man has been arrested on suspicion of murder over the unexplained death of a woman.
Devon and Cornwall Police were called to a property in Uglow Close in Camborne, Cornwall, on Tuesday morning by an ambulance crew over concerns for a woman's welfare.
Officers said a 31-year-old woman was taken to hospital where she was pronounced dead.
A 48-year-old local man was arrested and released on bail until November.
Emergency crews were called to the scene at about 09:45 BST and detectives said the death was being treated as "unexplained".
Another 48-year-old man, also from Camborne, was arrested on suspicion of being concerned in the supply of a controlled drug and remains in custody, police said.
The woman's next-of-kin have been informed.
Officers remain at the property and inquiries are ongoing, the force said.
