Slovakia’s Office for Personal Data Protection (UOOU) has called on the Czech investigative journalism website, Investigace.cz, to reveal who sent them a video, which had been recorded in the office of Slovakia’s former general prosecutor Dobroslav Trnka.
The video depicts Marian Kočner as he installs a camera in Trnka’s office. Trnka is also featured in the video.

“As a matter of principle, we protect our sources just like other good journalists do,” the website said in reaction to the letter. “Besides, we not only have the right but also the duty to protect them under European legislation.”
