The death of a 16-month-old girl in an east London hospital is being treated as murder.

A post-mortem examination found the young girl died of a head injury on September 17, Scotland Yard said.

The 16-month-old infant, from the Plaistow area, was taken to hospital after  falling ill  on September 13.

She died in hospital four days later on September 17.

On Tuesday (September 24), it was revealed Scotland Yard had launched a murder probe.

A force statement said: “The infant, from the E13 area, was admitted to an east London hospital after falling ill on Friday, 13 September.

“She died in hospital on Tuesday, 17 September. Officers know the identity of the child and next of kin have been informed. She is not being named at this stage.

“A post-mortem examination held on Monday, 23 September at Great Ormond Street Hospital gave cause of death as a head injury, pending further tests.

“Enquiries continue.”

A 36-year-old man was arrested on September 14 on suspicion of  causing grievous bodily harm.

He has been released on bail to return in mid-October.
