Polish prosecutors are investigating the publication of classified files from a probe into the illegal taping of government ministers.

The taping of government members revealed last year shook the Cabinet and cost the interior minister his position. Two waiters have been arrested and a businessman has been charged in the probe.

Hundreds of pages of files from that probe including personal data were published late Monday on a private Facebook account, prompting politicians to speak of an unprecedented leak that was undermining the state.

But a spokesman for Warsaw prosecutors, Przemyslaw Nowak, said Tuesday that it was instead a case of the illegal publication of classified information.

In line with the law, the files were available to the suspects, the plaintiffs and their legal representatives.
