A 50-year-old man has been arrested by detectives re-investigating the murder of a woman in Belfast 20 years ago.
Tina Wardlow, 32, was found strangled at flats in Majestic Drive in the Sandy Row area of the city in January 1993, two days after going missing on a night-out.
There had been an attempt to set the mother-of-four's body alight.
The suspect was detained in Co Londonderry on Tuesday morning by officers from the PSNI's serious crime branch.
He has been taken to Limavady police station for questioning.
