The mother and father of four young children who died in a 'gas explosion' at their terraced home have been arrested for gross negligence manslaughter.
Natalie Unitt, 24, and her partner Chris Moulton, 28, leapt from the first-floor window with their youngest child, Jack, two, after the inferno broke out on Tuesday.
The couple's sons, Olly, three, and Keegan, six, died alongside their daughter Tilly, four, and Miss Unitt's eldest child, Riley, eight, who was from an earlier relationship.
Mr Moulton is understood to have received treatment for burns and Ms Unitt for smoke inhalation - injuries which were believed to be non-life-threatening.

Staffordshire Police confirmed the man and woman were arrested at 1.30pm today.
Part of the roof collapsed, with the windows smashed and the inside appearing to have been blackened by smoke.
A fundraising page set up for the family of the four children has since reached over £28,500 - with more than 1,800 people donating money.
A spokeswoman for South Staffordshire Coroner's Court said the post-mortem examinations of the four children have not yet been completed but their file had been passed to the coroner.
Emotional tributes have been paid to the youngsters, with teachers describing them as 'bright, happy, loving and lively'.
Firefighters and police officers formed a guard of honour for the children as they were removed from the scene in Stafford by private ambulances
Police say four children died in the blaze and two adults, believed to be the children's parents, were rushed to hospital along with another child
