A schoolgirl was rescued from a mountain in Co Derry today after falling and knocking herself unconscious.
She was winched to hospital by a British army helicopter once teachers raised the alarm.
The girl (17) was in a party from Limavady College students hiking on Glenshane Mountain near Dungiven when the emergency began.
She fell while crossing a small river and hit her head, police said. Worried teaching staff used mobile phones to alert the PSNI as the victim drifted in and out of consciousness.
Police the Coastguards then arranged for a military helicopter from Ballykelly to fly to the scene.
A mountain rescue team was also called out to assist.
A PSNI spokesman said: "The girl was picked up by the helicopter and flown to the Causeway Hospital in Coleraine."
The girl was treated for minor injuries and discharged later.
