The woman, who is reportedly in her forties, was unimpressed with how her evening was panning out in the early hours of Thursday in Stockholm's Södermalm. She stole a knife from the kitchen of the club and began wielding it at other patrons. Police arrived soon after, and swiftly arrested the woman.
Stockholm police took to Twitter with a recount of events.
Nattklubbsgäst tyckte drinkarna var dåliga och det spelades för lite syntpop. Misskötte sig, åkte ut. Hotade gäst utanför med kniv. Greps!

"Nightclub guest thought the drinks were bad and there was too little synth pop. Misbehaved, left. Threatened guests outside with a knife. Arrested!" the oft-poetic policemen tweeted.
It remained unclear exactly what pushed the woman to threaten others, police spokesman Jan-Olov Lundgren told the Metro newspaper, newspaper. The woman, who was previously known to police, spent the night in jail on the suspicion of making illegal threats.
"Something happened out there that made the woman threaten the people standing there. The staff then notified the police," he said.
The Swedish police force is no stranger to social media, particularly the Södermalm unit in south Stockholm. Their unit boasts almost 20,000 followers on Twitter and nearly 15,000 on Facebook. The Södermalm force doesn't shy away from humour to share their messages either, receiving a flood of attention later on Thursday after tweeting: "Loud screams from an apartment worried neighbours who rang the police. It turned out to be a young couple in a toothpaste war. Not a crime."
Editor's note. An earlier version of this article indicated the reaction was due to "too much synth" when it fact it was "too little synth". The error has since been corrected
