Police are investigating the susepected murder of a 10-month-old baby after being called to a hospital by concerned doctors.
The child, a boy, was admitted to a north London hospital on Friday before being transferred to Great Ormond Street Hospital.
He died on Monday.
Although police know the identity of the child, he is not being named at the request of the family.
A post-mortem examination held last Thursday at Great Ormond Street Hospital gave the cause of death as head injury. Further tests are underway.
On Friday, a 31-year-old woman was arrested on suspicion of murder. She has since been bailed pending further enquires to a date in mid-October.
Detectives from the Homicide and Major Crime Command are investigating and enquiries continue.
