Two people have been arrested on suspicion of murder by Welsh police after two children and their aunt died in a fire.
Lee-Anna Shiers, 20, was killed after the blaze broke out in Prestatyn, North Wales, while her nephew Bailey Allen, four, and niece Skye Allen, two, also perished.
Their bodies were pulled from the first floor flat in Maes Y Groes after it was engulfed in flames on Friday night.
Firefighters managed to rescue Miss Shiers' partner Liam Timbrell, 23, and their son Charlie Timbrell, 15 months, who were rushed to Glan Clwyd Hospital by ambulance.
Mr Timbrell, who remains in a critical but stable condition, was later transferred to Whiston Hospital, Merseyside, while Charlie was moved to Alder Hey Children's Hospital in Liverpool.
North Wales Police on Saturday arrested two ground floor tenants, a man, aged 45, and a woman, aged 42, on suspicion of murder.
Detective Superintendent John Chapman expressed his sympathy for the victims' families and said: "There is a team of dedicated officers working on specific lines of inquiry in relation to this incident."
