Six children were rushed to hospital following the incident in the city's Shiregreen area yesterday – but two of them, aged 13 and 14, tragically died.
South Yorkshire Police released a statement this afternoon to say the other four children – including a seven-month-old baby – have now been relesed.
The force said in a statement: "Four children rescued from a house in Shiregreen yesterday have now been released from hospital."
The children, aged seven-months, three, 10 and 11, had reportedly been seen by neighbours being rushed into ambulances in bandages during Friday's frantic scenes.
Emergency services had initially been scrambled to the house over reports of concerns for safety.
But news quicky emerged of six children in hospital before police announced a 37-year-old man and a 34-year-old woman had been arrested on suspicion of murder.
Daily Star Online reported how two of the children told a pal they were "not coming into school" because they were "sick" just moments before they died.
