A 10-month-old baby boy is among three children who were found dead at a house in Bristol, England, on Sunday, police have said.
The other victims were a seven-year-old boy and a three-year-old girl, it is believed.
Officers were called to the property in the Sea Mills area of the city on Sunday morning by a member of the public concerned for the welfare of the people inside.
The victims, who have not been named by detectives, were found inside the property and pronounced dead at the scene just after 12.40pm.
A 42-year-old woman was arrested on suspicion of murder and taken to hospital to be treated for non-life threatening injuries. She remains in custody.
Post-mortem examinations are not expected to be completed until the middle or the end of this week “at the earliest”.
Detectives have not said whether the children were related to each other or the arrested woman.
Avon and Somerset Police has referred itself to the UK's Independent Office for Police Conduct watchdog over prior contact.
