A man whose body was found at a house in Carlton has been named as 58-year-old Anthony Fisher.
Detectives also announced a murder inquiry has been launched after a post mortem examination on Sunday confirmed he died after being stabbed.
Mr Fisher’s body was found at his house in Coningswath Road shortly after 3pm on Saturday.
No arrests have yet been made and detectives from the East Midlands Special Operations Unit have issued an appeal for information about any suspicious activity in the street in the days prior to the discovery.
Det Supt Kate Meynell said: “At this time, we are keeping an open mind as to the possible motive for this murder and are pursuing a number of different lines of enquiry.
“The assistance of the local community will be vital to our investigation. We very much want to hear from anyone who saw or heard anything that may have seemed unusual or out of the ordinary in Coningswath Road in the days leading up to the discovery of the victim’s body.
“Were there any individuals acting strangely or a vehicle which is not usually seen in the area, for example?
“If anyone has any information at all, no matter how insignificant you may think it is, we would like to hear from you as soon as possible.”
