A young child has died in an incident at a house near Larne, Co Antrim and a woman in her 30s and a baby have sustained injuries, police have confirmed.
Police said they are not looking for anyone else in connection with the child's death after an incident at a rural farmhouse on Bankhall Road on the outskirts of the Co Antrim town.
"Police can confirm that an investigation has commenced into the circumstances surrounding the death of a young child in the Larne area today," police said.
"A woman in her 30s and a baby are currently receiving hospital treatment for injuries.

A major police and emergency services operation has centred on the property at Bankhill Road throughout Monday.
Neighbours heard a helicopter and saw police and ambulances this morning.
A laneway to the property has been sealed off by officers and forensics experts are gathering evidence.
Neighbour Rhonda Kernohan said: "I heard the sirens and the helicopter, the air ambulance, came and it landed up at the back of the farm.
"We thought it was a farm accident but when we looked out there was a lot of shouting and a lot of police, a lot of ambulances about."
She added: "This is a quiet, rural, peaceful area."
Another neighbour said the woman who lived at the house was a "youngish girl".
They added: "It was very sad. We are feeling absolutely awful, so sad it is terrible.
"The shock of it, when it happens nearly on your doorstep."
The scene is at a house and outbuildings along a narrow lane high on a hillside overlooking Larne Lough, south of the port town of Larne.
