Police have launched a murder investigation following the death of a toddler in Co Tyrone.
Tavia Michella Ximenes Da Costa, who was 23 months old, was found dead at a house in the Windmill Court area of Dungannon on Sunday.
The child has connections to the East Timorese community in the town.
Three people - two women and one man - were arrested following the discovery.
Police had been treating the death as suspicious, but following the results of a post-mortem examination, it was now being treated as murder.
Detective Chief Inspector Anthony Kelly said: “Police, along with the Northern Ireland Ambulance Service, responded to the report of the sudden death of a child in the Windmill Court area of the town on Sunday morning, 13 October.
“Sadly, Tavia, who was just weeks away from her second birthday, was pronounced dead at the scene.
“Following the results of a post mortem examination, I can now confirm that I am treating her death as a murder.”
He added: “My thoughts, and sincere sympathy, are with little Tavia’s family members and loved ones whose worlds have been turned upside down”.
Mr Kelly also said that three people detained - a 21-year-old woman, a 24-year-old woman, and a 29-year-old man - were each arrested on suspicion of murder and remain in custody at this time.
It is understood detectives have been granted an additional 24 hours to question the three people in custody.
This will end on Thursday afternoon.
Police have appealed to anyone with information to contact them on 101.
