Detectives in the North investigating the death of a 15-year-old girl in County Armagh last weekend have arrested a 15-year-old boy.
Emergency services were called after the teenager fell unconscious in woodland in the Corcrain area of Portadown on Saturday night.
She was taken by ambulance to Craigavon Area Hospital where she died a short time later.
Police are investigating whether the death may have been linked to drugs.
The boy was arrested earlier today and interviewed - he's been released on police bail pending further inquiries.
This is the fourth arrest made to date by police investigating the tragic death.
