A 15-year-old girl has died from suspected drug use in Co Armagh, the PSNI said.
She died in hospital after being reported unconscious in a woodland area of Corcrain, Portadown, last night.
Chief inspector Joe McMinn said: "At this early stage of the investigation, one of our lines of inquiry is a possible link to drugs.
"A post-mortem examination will be carried out to determine the exact cause of death."
He said there was a large number of young people in the Corcrain area when police arrived and he appealed to anyone who was in that area and had information to contact them.
DUP General Election candidate David Simpson said: "A young life cut down so early. The scene is one of tragedy and devastation.
"I have spoken with the PSNI and youth agencies to ensure we have support services for those who require immediate counselling and feel this great loss."
Sinn Féin Assembly member John O'Dowd expressed shock and sadness.
