Anarchists Detained In Train Bombing

Investigators have detained two St. Petersburg anarchists and are looking for a North Caucasus native in connection with a blast that derailed a train on Aug. 13, injuring 27.

The anarchists were detained late last week in St. Petersburg, the news portal reported Monday. They have not been charged with any crime, it said, without providing further information.

Investigators, meanwhile, are zeroing in on the Caucasus native, whom villagers saw loitering around the blast site in the Novgorod region, Kommersant reported Monday.

Two villagers told investigators that the man had hired them to drive him around the area to find a suitable place to settle with his family a week before the explosion, the report said. He was seen shortly after the attack, getting into a car on a highway near the blast site.

The suspect is being sought by police in the republic of Karachayevo-Cherkessia and in the town of Mineralniye Vody in the Stavropol region.

Initially, investigators said they suspected that ultranationalists were behind the bombing of the train traveling from Moscow to St. Petersburg, and a police composite sketch of a suspect seen loitering around the blast site resembled a Slav. But investigators began examining a possible North Caucasus link seriously after a man called Radio Liberty/Radio Free Europe and claimed a Chechen rebel group was behind the attack.

Investigators currently are questioning all Chechen and Ingush natives who live in the Novgorod region, Kommersant said.

The train was derailed by what officials said was a homemade explosive device that contained the equivalent of 2.5 kilograms of TNT.

Some media speculated Monday that the derailing might have been the result of a mechanical failure rather than a bomb. A crater found at the site was only 30 centimeters deep and 120 centimeters in diameter, while it should have been much bigger if a bomb with the equivalent of 2.5 kilograms of TNT had been detonated, the reports said.
