A verdict of accidental death has been recorded on two teenagers who died after an arson attack on a council storage shed in Colwyn Bay.

Daniel Cleverley, who was 15, and Kirsty Burvill, 13, died last October half-term in the fire at Eirias Park.

Daniel Cleverley was found at the back of the shed

An 11-year-old boy who has been placed on a three year supervision order after admitting starting the blaze told police he did not know the teenagers were in the shed at the time.

The inquest in Llandudno, which resumed on Tuesday after a two week break, heard evidence from firefighters who attended the blaze.

One firefighter told the hearing the fire ripped through the storage shed with the ferocity of a "blow torch flame".

The blaze started when a six foot crash mat placed near the front door of the shed was set alight by a cigarette lighter.

The young victims were discovered in the back of the shed by a police inspector who knew them both.

Kirsty Burvill :' Bright and talented'

The fire had quickly spread to 10 other mats stored nearby, filling the building with acrid noxious smoke.

An expert from the government's Forensic Science Unit told the inquest there was 15 cubic metres of polurethane foam in the shed providing plenty of fuel for the flames.

The only access to the shed was by the vandalised front door which was where the fire had started.

The teenagers "had no way out," the expert said.

Earlier this month, the North Wales Central Coroner John Hughes expressed concern over the health and safety policy of Conwy County Council.

It followed details from several witnesses who said they had noticed the door of the shed was unhinged and insecure.

The inquest was told nobody had reported the incident to the local authority.

Mr Hughes asked Paul Frost, assistant director of Conwy council's leisure department: "It's quite clear, isn't it, that if the premises had been secure Kirsty and Daniel wouldn't have been able to get in?

"It's as simple and prosaic as that?"

Mr Frost replied: "Yes."

'Sense of awareness'

Speaking during the earlier hearing Daniel's father, David Cleverley, said his son would never purposefully do anything wrong and would not enter a building if it was secured.

Geoffrey Burvill, a retired local government officer, described his daughter as bright and talented with a civic sense of awareness and said Daniel was a caring youth.

The victims of the blaze had been dating for a couple of months when the tragedy happened.

The 11-year-old who admitted starting the blaze was placed on a three-year supervision order last December.

He admitted arson and the prosecution told a youth court at Llandudno that it was accepted that he had not realised the pair were inside the building.

Hundreds of mourners attended separate funerals held in the town for the pair.
