Two people arrested on suspicion of murder following a fire in Prestatyn in which four died have been released from police custody.
Police say a 42-year-old woman has been released on bail pending further inquiries, while a 45-year-old man has been released without charge.
The fire claimed the lives of Lee-Anna Shiers, 20, her 15-month-old son Charlie, nephew Bailey Allen, four, and two-year-old niece Skye.
Charlie's father Liam Timbrell, 23, is understood to remain in a critical but stable condition at Whiston Hospital in Merseyside.
Yesterday relatives of the family thanked the community and emergency services for their support.
