WARSAW -- Polish officials have revealed that a Russian citizen was arrested in Warsaw and charged with spying for Russia, RFE/RL's Russian Service reports.
The Polish Internal Security Agency discovered equipment for encrypting messages at his house during the arrest, Polish media reported.

Poland also expelled 10 Russian diplomats in 2000, reportedly for spying activity.
