A 19-year-old girl who died after becoming unwell at her Debs in Co Galway has been named as Jessica Moore.
The teenager from Bullaun in Loughrea had been attending the St Raphael's College dance at a hotel in Ballinasloe.
Her friends called an ambulance after she reported feeling unwell at around 2am this morning.
She was taken to Portiuncula Hospital where she was later pronounced dead.
The Coroner has been notified and a post-mortem examination is due to take place tomorrow.

The student, a star of her school's musicals, would have been due to receive her Leaving Cert results tomorrow. She had only celebrated her birthday last month.
In her death notice on Rip.ie, "the inexpressible grief" of Jessica's "heartbroken" parents Brendan and Catherine is recounted.
The teenager is described as a "cherished and much-loved sister" to her two siblings and will be sadly missed by her family and "many, many friends".
