Police are appealing for information after a pensioner originally from Ireland died after bursting into flames on a London street.
The man caught fire in Haringey shortly after 1pm on Sunday September 17 where emergency services were called to a "man ablaze".
Members of the public made efforts to put the fire out and called police.
The fire was quickly extinguished and the man was taken to a specialist hospital by London's Air Ambulance.
The man was 70-year-old John Nolan who was originally from County Mayo in Ireland, but was living in Tenterden Road, N17.
Mr Nolan was a retired construction worker who was unmarried.
A post-mortem examination on September 27 gave cause of death as severe burns. An inquest will open at Barnet Coroner's Court on March 13 2018.
The cause of the blaze was investigated and no accelerant was found.
The death is being treated as unexplained and detectives are investigating to establish the cirucmstanes.
PC Damien Ait-Amer, said: "We have spoken with a number of witnesses who saw Mr Nolan ablaze, but we have yet to establish how the fire started.
"Mr Nolan was a well-liked member of the community and none of our enquiries so far have indicated that he had been involved in a dispute of any sort. Nor does any account given by witnesses suggest that he had been in contact with another person at the time of the fire."
"Anyone who witnessed the incident but has yet to speak with police is urged to call PC Damien Ait-Amer via 101. You can also tweet information to police via @MetCC.
