ATHENS – A prosecutor called for an immediate probe into threats made by a member of the notorious anarchist group Rouvikonas to burn down the building housing the SKAI TV and radio station, as officials scrambled over a bomb threat against the Interior Ministry.

In a post on social media, Giorgos Kalaitzidis openly threatened to “burn down” the broadcaster, prompting prosecutor Ilias Zagoraios to order the probe with no explanation why Kalaitzidis wasn’t arrested after giving his name.

“We will burn Skai down. Today, tomorrow, in 10 years – I don’t know. But we will burn it down. And we will dance around the ashes,” Kalaitzidis wrote.

That came as police in the Greek Capital cordoned off the area around the Interior Ministry on Vassilissis Sofias Avenue near central Syntagma Square to a bomb squad could investigate although the 10:30 a.m and noon deadlines passed without an explosion as anonymous callers said would happen.

Rouvikonas has gone on dozens of assaults, many of them violent, against a range of targets including foreign embassies, the grounds of Parliament, the Defense Ministry and other government offices but only a handful of alleged perpetrators have been charged.
