A Swedish soldier has been convicted of negligence and fined 21,000 kronor (£1730) for leaving a USB memory stick with military secrets in a public computer.
The Stockholm court says the memory stick contained classified information about improvised explosive devices in Afghanistan. It was found by an unidentified person at a university in Stockholm and handed over to investigators.
The 31-year-old soldier admits accidentally leaving the USB stick in the computer, but claims he wasn't aware the information was classified. It wasn't immediately clear whether he would appeal.
Wednesday's ruling says he acquired the information while serving as a peacekeeper in Afghanistan in 2006 and was supposed to have handed it in when his mission ended.
