Police in Northern Ireland say they have arrested a man on suspicion of murder, following the death of a two-year-old girl.

PSNI detectives are investigating the circumstances of her death on Friday.

The child was admitted to hospital after ambulance personnel attended an address at Park Avenue, Dungannon in Co Tyrone.

The child later died in hospital.

Detective Chief Inspector John Caldwell says a 32-year-old man was arrested on suspicion of murder as part of the investigation.

He remains in custody.

A post mortem is set to be carried out to establish the cause of the child's death.

Her family is being supported by Family Liaison Officers, the PSNI adds.
