A cigarette is the most likely cause of a devastating blaze which killed the three young children of a Pontefract mum.
Fire investigators looking into the tragedy have concluded that a cigarette which had not been put out properly is the most likely cause of the fire, which happened on Nov 11 and claimed the lives of William Beale, nine, Anthony Hudson, five, and Maddie Hudson, three.
The children's mother Samantha Hudson, 27, from Fitzwilliam, near Pontefract remains seriously ill in hospital.
She was found clutching the children in her arms after flames tore through their home.
The mum is understood to be unaware that her children have died.
As reported in the YEP, the fire broke out at the property in Clarence Avenue, Bridlington, just before midnight on November 11.
Police had already investigated and had concluded that there was nothing to indicate the fire was started deliberately.
Since the fire, Humberside Fire and Rescue Service investigators have been carrying out detailed examinations to determine what caused the blaze.
And this week, a spokesman said: "Following the fatal fire on Thursday, November 11 2010 in Clarence Avenue, Bridlington an investigation has been ongoing to ascertain the exact cause of the fire.
"Fire investigators have been working with the police and forensics experts and it has now been confirmed that the most likely cause of the fire was due to a cigarette which had not been fully extinguished."
Last month, the YEP reported that Miss Hudson's family had said they thought the fire may have been started by a phone charger.
