Police are investigating after a man and woman were found dead inside a house.
The bodies were discovered at a property in Caister-on-Sea, Norfolk, after police forced their way in.
A spokeswoman for Norfolk Constabulary said police were called to the house in Upper Grange Crescent around lunchtime yesterday after concerns were raised about the safety of the occupants.
Officers sealed the address while forensic investigations took place.
The deaths of the pair, who have not yet been identified, are being treated as unexplained, police said.
Post-mortem examinations will take place later today.
A window cleaner raised the alarm after calling at the property on his rounds, police said.
He had become suspicious because of bottles of milk lined up outside the home.
The deaths are being treated as a mystery but it is not thought there were any obvious signs of injury or a disturbance.
