The deaths of three children found at a house in Surrey with their father are being treated as murder, police have said.
Dominik Swiderski, aged three, and his brothers Nikodem and Kacper, both aged two, were found dead in Staines on Saturday.
Their father had been identified by police as Polish national Piotr Swiderski, aged 31.
Surrey Police said inquests into all four deaths would take place in due course.
“We are not looking for anyone else in connection with our investigation. Their mother is being supported by specially trained officers,” the force said.
Police previously said it had referred itself to the Independent Office for Police Conduct (IOPC), due to previous contact with the family.
