Moscow bomb threat man arrested

Police wrestle with a man who threatened to blow up a car filled with explosives

MOSCOW, Russia (CNN) -- A man who threatened to blow up a car laden with 1.5 tons of explosive outside the ex-KGB offices in Moscow has been arrested.

Police are questioning the man who also said he had an automatic rifle, the Russian police press service said.

But a search of the vehicle only revealed cement, the agency said.

Traffic had come to a halt after the man threatened to blow up a car near the Russian Federal Security Service headquarters, the successor to the Soviet-era KGB, at about 2.30 p.m. (1130 GMT) on Thursday.

He had demanded to speak with high-ranking government officials.

Witnesses said police and the man negotiated for more than 90 minutes, news reports said.

The area was later re-opened.

Russia is marking a day of mourning for the 116 servicemen killed in a military transport helicopter crash over Chechnya on Monday. (Full story)
