Police said the arrests of Mairead and Mick Philpott were part of a complex and lengthy investigation
Police have been given another 12 hours to question the parents of six children killed in a house fire in Derby.
Mick Philpott, 55, and his wife Mairead, 31, were arrested on suspicion of murder on Tuesday morning.
Five children, aged between five and 10, died in the blaze at their home on Victory Road on 11 May. Duwayne, 13, died three days later in hospital.
A trust set up to handle money raised for the family said it would continue its work despite the developments.
Jade Philpott, 10, and brothers John, nine, Jack, eight, Jessie, six and Jayden, five, were pulled from the house by firefighters but were pronounced dead at the scene.
Mr and Mrs Philpott held a press conference five days later to thank the community for their support.
Detectives have confirmed the fire began inside the front door and an accelerant – most likely petrol – was used.
Mick Philpott made headlines in 2006 after asking for a larger council house for his family
Speaking after Tuesday’s arrests, Assistant Chief Constable Steve Cotterill said: “In view of the arrests, I would urge anyone who may have been holding back, not felt comfortable to voice their concerns or not had the confidence, to do so now.
“The latest arrests are just one step further in the investigation. It is absolutely vital that if you know anything you think could help us, come forward now, do not wait any longer.
“What we need to do now is carefully take our time, question the two individuals concerned and piece it together with everything else we know to date.”
The house is still the scene of forensic examination and is likely to remain so for some time, he added.
The DJ Trust, which is administering money donated to the family, has stated the cash was only ever being raised to cover the costs of the funeral arrangements for the children and is therefore unaffected by the arrests.
A spokesman added the six funerals would cost a huge amount of money but anything left over was likely to be donated to charity.
On Twitter it posted a message saying “Please Just Remember, the DJ Trust is hoping to raise enough for the 6 Angels, regardless (of) what’s in the news, the 6 Angels were still taken.”
The family attracted attention in 2006 when Mr Philpott asked the council for a larger house to accommodate his wife, girlfriend and 14 children.R Soft Web Hosting
