Michael Polding death: Website to help trace Ricardo Pisano
A website to assist Sussex Police in tracing a suspect being sought over the unsolved murder of a Brighton man has been set up by the force.
The body of Michael Polding, 62, was found at his flat in July, and may have been there for two months.
In September, police offered a £5,000 reward for information leading to the arrest of his friend, Ricardo Pisano, also known as Brandon Victor Pillay.
The website shows pictures of the suspect, also known as Ricky and Ree.
Mr Polding was an openly gay man who moved from Scotland to Croydon, south London, with his partner in the 1970s.
'Justice for Michael'
His partner died in 2001 and last year he moved to Brighton.
A post-mortem examination found Mr Polding suffered a number of injuries.
Police said they did not believe his death was a random attack or linked to any hate crime as a result of his sexuality.
Det Ch Insp Nick May, who is leading the investigation into his death, said: "It has been nearly five months since Michael's body was found in his flat in St George's Road but our investigation into his death continues.
"We are determined to get justice for Michael and his family and this case will remain open until we do so."
He added that Mr Pisano had links within the UK - in Brighton, Croydon and Crouch End in London, and Southampton - as well as across the world, including New Zealand and South Africa.
"The last positive sighting of him was in the Marlans shopping centre in Southampton at the end of July.
"He changes his appearance and his identity so it is important that people take a good look at the photographs and don't assume he will be introducing himself as one of the names currently known to police," Det Ch Insp May said.
Mr Pisano, is thought to be aged in his 30s and has a South African accent.
He is believed to have walked out of an open prison in New Zealand 10 years ago after being convicted of fraud offences.
Police believe he was the last person to see Mr Polding alive.
Anyone who has any information is asked to contact Sussex Police.
