A teenage girl, understood to be from Letterkenny, was one of three teenagers hospitalised after a “drinking party” in Strabane last night.
A group of up to 60 youths gathered at Strabane Golf Course for an event believed to have been organised on social media.
The Golf Course Road was closed for several hours as police cleared the area and paramedics tended to a number of young people suffering from the ill effects of alcohol.
A PSNI helicopter was called out to search the area after the girl from Donegal was unaccounted for.
She was later found unconscious and taken to hospital where she is now recovering.
Another female and a male, both aged 16, were also found unconscious near the banks of the River Mourne.
