South Korean detained earlier this year is accused of espionage in Russia

A South Korean citizen arrested in Russia earlier this year on suspicion of spying is to remain in custody until mid-June, Russia’s state news agency Tass said Monday.
The news agency said it is the first time that a South Korean has been arrested for espionage in Russia.
Tass said the man, identified by the agency as Baek Won-soon, was detained “at the start of the year” in the far eastern city of Vladivostok and was taken to Moscow at the end of February. He is being held in Lefortovo Prison, where a court on Monday ordered his detention extended until June 15, Tass said.
Tass cited an unnamed law enforcement official as saying the suspect passed on information “constituting state secrets to foreign intelligence services.” The case has been labelled “top secret” and no further details have been made public.
