The reveller, who hasn't been named, was left on her own when everyone else went home after an under 16s Sixth Form disco at Manhattan's nightclub in Barrow, Cumbria. She didn't wake up until staff had locked the doors and left and wasn't discovered until 8.30am the next day, when cleaners arrived and let her out.
