This is the first picture of a man who died after being found on fire in Mitcham, as murder detectives named the victim.
Emergency crews scrambled to Commonside East just after 6am on Thursday to reports of a man on fire. Officers attended and the body of a man was found.
Murder detectives have identified the man as Loeike Guei, who was aged 23 and lived in Thornton Heath.
Mr Guei's death is being treated as suspicious by police. His family are aware and are being supported by specially trained officers.
A post-mortem examination on Friday gave his preliminary cause of death as a head injury.
Metropolitan Police said no arrests have been made and a crime scene remains in place as the Specialist Crime Command investigates.
Detective Chief Inspector Wayne Jolley, who is leading the investigation, said: ”Loeike’s family have been intensely shocked by the loss of their loved one and are at the very beginning of coming to terms with their grief.
"Foremost in our thoughts are their welfare – they are being supported by specially trained officers and we ask that their privacy is respected at this terribly sad time.
“We are in the initial stages of our investigation and are keeping an open mind with regards any motive. We are making good progress, following a number of leads and have spoken to a number of people already."
He added: "What I need now is for anyone who has not spoken to us yet but has seen any suspicious activity or vehicles in the vicinity to make contact with us immediately.
“You may have information that may seem insignificant but could prove crucial to our investigation.
"I urge you to contact us immediately, or tell us what you know via Crimestoppers if you wish. What matters most is that you make the call.
"Loeike’s family are traumatised and we need the support of the public in bringing them justice.”
