PSNI Det Chief Insp 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, October 13th.
“Sadly, Tavia, who was just weeks away from her second birthday, was pronounced dead at the scene.
“Following the results of a postmortem examination, I can now confirm that I am treating her death as a murder.”
He continued: “My thoughts, and sincere sympathy, are with little Tavia’s family members and loved ones whose worlds have been turned upside down.
“Three people, two women and one man, were arrested in connection with the toddler’s murder.
“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.”
Detectives are appealing to anyone with information to contact them on 101, quoting reference 436 of October 13th.
Sinn Féin MLA Colm Gildernew said he was “horrified and deeply saddened” to hear that the death was now being treated as murder.
He added: “This is absolutely heartbreaking and my thoughts are with Tavia’s loved ones as they process this truly awful situation.
“I would make an appeal for anyone with information which could assist in this investigation to immediately bring it forward to police.” – PA
