A man was arrested last night after the discovery of a woman's body in west Belfast.
The woman, named locally as Theresa Gray, was found dead at a flat in the Magnolia Park area of Twinbrook. The grim discovery was made shortly before 2.30pm.
It is understood the woman, who was in her 40s, had a six-year-old child.
Police were trying to establish how the woman died.
A PSNI spokesman said: "One man has been arrested and is currently in custody helping police with their enquiries."
Meanwhile, in Co Londonderry a body was recovered from the River Bann, near the Barmouth at Castlerock Beach yesterday.
At around 5.30pm, the body was pulled from the water by the coastguard after a man in a passing boat reported seeing something afloat in the river.
The victim has not yet been identified, but last week a major land and sea search was launched after a man fell into the Bann.
He was named locally as Jonathan Kane (26) and was said to be from the Coleraine area.
Witnesses saw him fall into the river near Sandalford Bridge in Coleraine and raised the alarm.
Sean McCarry, unit commander for the Coastguard of Northern Ireland, had been involved in a subsequent search for the body.
He said the recovered body has not been formally identified but no other persons had since been reported missing in the area.
"The family would have been told it could have been weeks before a body was recovered so we are pleased that the body has been found," he said.
