2 Suspects Detained in Chubais Ambush

Two more suspects have been detained on suspicion of participating in a roadside ambush on Unified Energy Systems chief Anatoly Chubais last month, and the Basmanny district court sanctioned their arrests late Thursday.

The suspects, Robert Yashin and Alexander Naidenov, are retired paratroopers who once served under the command of former special forces officer Vladimir Kvachkov, who has been arrested on charges of organizing the March 17 attack.

The Prosecutor General's Office refused to comment on the detentions.

Investigators tracked down Naidenov and Yashin through plastic mats left in the snow by the gunmen who fired on Chubais' armored car and an accompanying vehicle in the Moscow region, Kommersant reported Thursday. No one was injured in the attack.

Traders at a local market told investigators that the mats were bought by men driving an Italian-built Lancia sedan, a rare sight in Russia, the newspaper said.

Police detained the Lancia's owner, former special forces officer Igor Kravatko, in Tver. Kravatko said that several days before the attack, Yashin, an old army friend, had asked him to help buy a car battery, wires and other items -- which investigators believe were used to assemble a bomb. A powerful bomb went off near Chubais' car before the gunmen opened fire.

Kommersant, citing a source in the investigation, said Yashin, Kravatko and Naidenov had spent time at Kvachkov's dacha and that the bomb was built there.

Naidenov and Yashin were detained in Moscow on Wednesday.

Kvachkov's lawyer Vladimir Levin said Thursday that his client knows only one of the suspects, but did not specify which one, Interfax reported.

Naidenov's lawyer Ruslan Koblev said his client was ready to prove in court that he was nowhere near the site of the attack. He also said Naidenov was jailed for several months for illegal weapons possession in 1997.

Chubais' lawyer Anatoly Kucherena praised investigators for tracking down the suspects and suggested the attack had been perpetrated by "devout ultranationalists who are former officers of the special services and armed forces."

Kvachkov, a veteran of the Afghan and Chechnya wars, was charged with plotting the attack earlier this month. Kvachkov has maintained his innocence and refused to cooperate in the investigation. His son Alexander, a retired military officer and a suspect in the attack, is being sought by investigators.

Interfax said Thursday that investigators also were looking for a friend of Kvachkov. The report only identified the woman by her last name, Zhitnykh.
