A man whose body was found after a fire at a New Barnet flat was actually stabbed to death three days before the blaze broke out, according to police.
Antonio James Tammaso, 49, was found dead after a fire broke out at a flat in Sheridan Lodge, Potters Road, on 15 May.
A murder investigation was launched after a post-mortem examination revealed he died of multiple stab wounds - well before the flat was set alight.
Detective Chief Inspector Glen Lloyd is now appealing for the public's help to gather clues surrounding his death - in particular, if anyone saw someone carrying a red petrol can.
Lloyd said: "We are appealing for the public's help in this investigation.
"We believe, following Mr Tammaso's murder, the suspect or suspects came back to the flat two to three days later and set fire to the property.
"We would like to hear from everyone who knew Mr Tammaso to build an understanding of who he was. Who did he socialise with? Who would he be seen with?
"Mr Tammaso would have been known locally, frequenting the New Barnet area, especially around Potters Road often riding his bike.
"We would also be keen to hear from anyone who may have seen or heard anything suspicious at Sheridan Lodge in the days before the fire.
"Especially anyone who would have seen someone carrying a red petrol can, like the one the pictures we have released today. Maybe someone saw its owner filling it up at a local petrol station? Or walking to, or from, one? If you did, please call us."
