A 19-year-old woman who passed out in a U.K. nightclub restroom stall had to call police for help after discovering she’d been locked inside the venue.

She’s believed to have been partying with friends in the club last Thursday evening into early Friday morning.

Officers contacted club managers, who returned to the club to let the woman out, reports the Manchester Evening News. Managers are looking into how staff failed to find the woman before locking up.

Inspector Phil Spurgeon of the Greater Manchester Police says when he spoke to the woman Friday morning, she seemed to be alright, despite feeling embarrassed.

Have you ever been locked inside a building? I’ve always thought it would be fun to be locked inside the new Foothills Mall when it opens – I wouldn’t steal anything, but it would be nice to check out the new mall without the crowds.
