A convicted paedophile who committed suicide left a note outside his flat warning people not to enter, an inquest heard today.

Ryan Heaphy was found dead at a flat in High Road, New Southgate, on April 10 2014.

He had locked himself in the kitchen of the first floor flat where he was killed by carbon monoxide poisoning caused by barbecue fumes.

A sign had been posted on the door saying "Danger, do not enter. Estimated life span one minute”.

London Fire Brigade evacuated people living in the surrounding flats and police arrived at the scene just after 7.30am.

Mr Heaphy's body was found at 10.50am surrounded by smoke.

Recording the verdict as suicide, coroner Andrew Walker said there was little doubt his intention was to bring about the end of his own life.

Mr Heaphy was arrested in Brentwood, Essex by Essex Police on January 29 after more than 23,700 indecent images of children were found on his computer by his partner.

He pleaded guilty to two counts of making indecent images of children at Basildon Magistrates’ Court three days before his death.

He was due to be sentenced on April 28, at Basildon Crown Court, Essex Police said.
