A man has died in a house fire on Boxing Day.
Firefighters found the body of the man inside a property in Rose Hill Street, Normanton, Derby, at 14:10 GMT and police were called.
Formal identification has not taken place, and an investigation into the cause of the fire is in its early stages.
Police have asked anyone with CCTV or dashcam footage from the area between 11:00 and 13:45 to come forward.
Derbyshire Fire and Rescue Service said crews were "met by a well-developed fire on the first floor of the two-storey mid-terrace property".
Neighbour Afzal Ramzan, who lives two doors down from where the fire happened, said: "I was in the house yesterday and the children were playing in the garden and saw the smoke. They came inside, told us and we phoned the fire brigade.
"We started knocking on the neighbour's doors to see if anyone was in there, but no-one opened the door."
He added: "We have known them for years. It is sad what has happened."
Rose Hill Street remained closed on Friday afternoon.
