Two schoolgirls from Stockholm, Sweden, are being taken to court after allegedly placing bugs to record their teachers in the school staff room.

The two girls allegedly wanted to listen to the teachers during a conference in which students' grades were decided. According to Swedish news site The Local, the two hoped the information they gleaned from the recordings would help them improve their grades.

They were caught when one decided to publish details of the caper on her Facebook page.

They have been fined approximately $270 US each and charged with trespassing.
