A murder investigation launched more than a year ago is continuing.

The body of 63-year-old Leslie Smith was found inside his Suffolk Square flat in Norwich on Sunday, October 17, 2021.

His death was initially treated as unexplained until a post-mortem revealed Mr Smith may have suffered an injury.

A Home Office post-mortem examination was carried out on October 24, 2021 and while the cause of death remains inconclusive, unlawful injury cannot be ruled-out.

Detectives launched a murder inquiry and have been working to establish the circumstances surrounding Mr Smith’s death.

A Norfolk Police spokesman said enquiries were "continuing".

CCTV footage has been released which shows a man carrying a backpack walking in Park Lane, off Earlham Road, on October 5 last year, shortly before 7.40pm.

Police are keen to hear from anyone who recognises the man in the CCTV or maybe themselves in the footage or who has information about the incident.

Two people, a 38-year-old man and a 37-year-old woman, were previously arrested on suspicion of murder but released under investigation.

Information to police on 101.
