A 17-month-old toddler has died after being found floating in a swimming pool at the home of her foster parents.
Anna Hider was found unconscious in the purpose-built pool in her garden in Havant, Hampshire, on Sunday night.
Attempts were made to resuscitate her before paramedics arrived. She was pronounced dead in hospital in Cosham.
The death was being treated as a "tragic accident" and there were no suspicious circumstances, police said.
Further attempts were made to revive the toddler after she arrived at the Queen Alexandra Hospital, but she was pronounced dead at 2149 BST.
Officers from the Specialist Investigations Department are investigating the death on behalf of the coroner and a post-mortem examination will be conducted, a Hampshire Constabulary spokeswoman said.
"Due to the sensitive nature of this inquiry and the sensitive circumstances surrounding it we will not be releasing the address of where this occurred," she said.
"It's not in the public interest to release the information. It would do more harm than good."
Portsmouth City Council confirmed that Anna, who was from the city, was in foster care.
Councillor Gerald Vernon Jackson said: "We offer our sincere condolences to the family of the child who tragically died yesterday.
"The child was the subject of an interim care order and we are offering every support possible to all those who have been affected by this.
"The city council will also carry out our own review of the circumstances."
