Detective Chief Superintendent James Conway who leads policing for Hackney and Tower Hamlets, said: “This is an extremely distressing incident which will understandably cause shock and disbelief amongst the local community and those who attended the scene.
“We are working with our partners, including Hackney Council and the school community, to ensure support is there for people who need it.
“Specialist officers from our homicide team are progressing this investigation and continue to work to establish the circumstances of this young child’s death, and the events that led up to it.
“This incident occurred within the home and, while is no wider public safety risk, additional officers will be present in the area as we recognise the impact this will have on the community.”
