Tributes have been paid to a teenage girl who died in Tavistock after apparently taking an unknown substance.
The girl was airlifted to Derriford Hospital on Saturday afternoon after being found by ambulance crew close to the disused viaduct near Crowndale Road.
The 15-year-old died in hospital a short time later. Her next of kin have been informed.
Following the incident a 14-year-old boy was also taken to the same hospital where he is now recovering.
Police have launched an investigation and believe that both teenagers suffered adverse reactions having taken an as yet known substance.
Officers seized an unknown substance from the scene and say this will be tested to find out what it is.
Cards and flowers have been left at the place where the girl was found by ambulance crews.
Tributes have been paid by many in Tavistock, including the Town Mayor Paul Ward who says the town is "very shocked and deeply saddened".
"We know that drugs can be obtained in Tavistock, just as they can in any town. We understand that it's no more of a problem here than it is in any comparable town."
"It's a natural feature of adolescence to explore and experiment, but I think all I can do is repeat the advice given me by the police - that parents should try to be aware of what their children are doing and discuss with them the dangers of taking street drugs and other substances."
The girl was a student at Tavistock College and Principal Sarah Jones said students were "being offered support when they need it", a book of condolence had been organised, and plans for a memorial service were under way.
