Moscow's Kursky Station was evacuated Wednesday morning after a grenade was discovered in one of the terminal buildings, a news report said.
About 200 people were evacuated shortly after 6 a.m. when engineers at the station found a grenade without a detonator, the RIA Novosti news agency cited a law enforcement source as saying.
The suspicious item appeared to be an F1 grenade, the report said. The F1 has a destruction radius of about 200 meters.
The discovery comes just a day after Moscow transport police took a 24-year-old man, Alexander Kovnev, to court for allegedly reporting 11 hoax bomb threats at the Kursky station in the space of just four months, the TASS news agency reported.
If convicted of knowingly disseminating false information about a terrorist act, Kovnev could face up to three years in prison or a fine of 200,000 rubles ($4,000), the report added.
Local police are yet to officially confirm the discovery of the grenade.
