Tallinn - Authorities in Estonia have arrested a former high-ranking official in the defence ministry and his wife under suspicion of treason, local media reported on Monday.
The prosecutor's office said Herman Simm collected classified information and passed it on to representatives from another country.
The authorities will not release any details about the case, nor will they say which country hired the alleged spy, Gerrit Maesalu, spokesman for the State Prosecutor's Office, told Postimees Online.
However, citing unofficial information, the Baltic News Service has reported that Simm worked for Russia, making him the first official suspected of treason since Estonia broke away from the Soviet Union in 1991.
