Police investigating the deaths of four people in a house fire have said they cannot rule out the blaze being linked to the murder of a man in a nearby street.
The four - whose details have not been released - died after emergency crews were called to the terraced property in Leicester.
Police and firefighters attended the burning building at Wood Hill, in the Spinney Hills area, around 12.35am, several hours after a man was attacked half a mile away in Kent Street.
The victim, in his 20s, was assaulted at around 5.30pm and was taken to Leicester Royal Infirmary where he died.
A Leicestershire Police spokesman said: "Police were called at around 12.35 this morning by the fire service following a report of a fire at a house on Wood Hill, Leicester. On attendance it was reported that occupants were still inside the property and four people were found deceased in upstairs bedrooms.
"The fire, which caused extensive damage to the property, was extinguished by the fire service and the property has been cordoned off to allow for a full forensic examination. The circumstances and cause of the fire are currently under investigation and officers would ask anyone who has any information regarding the incident to please contact them.
"We are unable to rule out at this stage if this incident is linked to anything else we are investigating."
A post-mortem examination is due to take place on the murdered man and Detective Chief Inspector Simon Cure said the investigation was "in its very early stages".
This morning a police cordon was placed around the burned-out property and white-suited forensics teams and fire investigators hunted for clues.
Hashim Bahadur, 58, a businessman who works across the road from the gutted house, said: "Police have closed everything down. We know that four people have passed away in the terraced house - it is so sad."
