Girl dies after taking 'unknown substance' in Tavistock
A 15-year-old girl has died after she was found unwell near a disused viaduct, having apparently taken an unknown substance.
A 14-year-old boy who was discovered with the girl near Crowndale Road in Tavistock, Devon, remains in a critical condition.
The pair were airlifted to hospital at about 16:15 BST on Saturday, but the girl died shortly afterwards.
Devon and Cornwall Police said they were found close to a disused viaduct.
Officers believe both teenagers had "suffered adverse reactions having taken an, as yet unknown, substance or substances".
The girl's next of kin have been informed and officers are supporting her family.
Police have seized an unknown substance from the scene and carrying out tests to establish what it is. No arrests have been made.
Insp Pete Turner said: "I would like to stress that initial enquiries show that this is an isolated incident involving these two young people and we do not believe that there is any wider risk to the Tavistock community.
"We would however urge all parents and carers to speak to their children and young people about the risks of taking unknown substances."
Police are appealing for anyone who has information about the incident, including people in the area around the viaduct on Saturday afternoon.
