A man has been arrested on suspicion of murdering a one-year-old boy.
Bidhya Sagar Das, 33, was arrested in Hackney at 7.15pm on Sunday 19 March following a police hunt.
He has been taken to an east London police station where he remains in custody.
Police were called at around 11.10pm on Saturday, 18 March, after two children were found fighting for their lives at a flat in Wilberforce Road, N4.

The boy and girl – both one-year-old – were rushed to hospital where the boy was pronounced at 12.48am on Sunday.
The girl remains in hospital in a critical condition.
A murder investigation has been launched, led by Detective Chief Inspector Dave Whellams.
“This is clearly a tragic incident,” said DCI Whellams.

“Our thoughts are with the family of the two young children. Despite the best efforts of medical professionals, a baby boy sadly died in the early hours of this morning. A baby girl currently remains in a critical condition and is receiving specialist medical care.
“Whilst we remain in the early stages of the investigation, a man has now been arrested. I would still like to hear from anyone who may have any information regarding this terrible incident.”
Anyone with information that may assist the investigation is asked to contact the police on 020 8345 3775 or Crimestoppers on 0800 555 111.
