A man has been arrested on suspicion of murder after two children were stabbed to death in Ilford.
The 40-year-old man was arrested on Wednesday at a London hospital where he is currently receiving treatment, police said.
He remains in hospital under police guard.
Pavinya Nithiyakumar, who was 19 months old, and three-year-old Nigish Nithiyakumar died after suffering knife wounds in the incident on Sunday.
Police rushed to their home in Aldborough Road North at around 5.30pm to reports of a man and two children injured.
Pavinya was pronounced dead at the scene and Nigish was taken to hospital by the London Ambulance Service but died after arrival, Scotland Yard said.
Police said all those involved in the incident were known to each other, with the children’s mother being supported by specially trained officers.
Detective Chief Inspector Vicky Tunstall said: “The ending of these innocent young lives is extraordinarily tragic and we are working hard to fully understand what may have caused this to happen.
“Whilst I know the effects of this crime are reverberating throughout the local community, please be reassured that we are not seeking any other person(s) in connection with the deaths and there is no cause for the community to be fearful or alarmed.
"I would like to hear from anyone who feels they may have information that could assist our investigation to understand this horrific tragedy.
