18 March 2005 -- Russian prosecutors have confirmed authorities have detained a man on suspicion of trying to kill the head of Russia's electricity monopoly, Anatolii Chubais.
Russian newspapers and agencies report that the suspect is a retired military officer. But there has been no official confirmation of this.
On 17 March, Chubais escaped unhurt when assailants hidden in trees detonated a roadside bomb and sprayed his convoy with automatic fire as he drove to work.
Chubais is one of Russia's best-known figures and the architect of Russia's post-Soviet privatization program.
