Two Stockholm schoolgirls have been slapped with a fine for bugging the staff room at their seat of learning.
According to The Local, the mid-teens pair intended to listen in to a meeting convened to decide pupils' grades in the hope they might "glean information that would enable them to get their grades improved".
Handily, they managed to get their hands on a key to the room, and the night before the planned get-together planted some off-the-shelf bugging kit they'd bought in a local "gadget store".
At this point, sadly, one of the two broke a basic rule of espionage and boasted about the clandestine op on Facebook. Cue an appearance in Stockholm District Court, where they were each fined 2,000 kronor (£174) for trespass and the rather sinister offence of "arbitrary conduct". ®
