Police have arrested another suspect in the attack on an environmental activist who opposed a controversial road building project near Moscow, investigators said on Thursday.
Three other suspects, including a Moscow region official, were arrested earlier this week.
Konstantin Fetisov was set upon by men with a baseball bat on November 4.
Fetisov had protested against government plans to chop down part of a mature forest in Khimki to make way for a multi-lane motorway linking Moscow to St. Petersburg.
The project was given the go-ahead on December 14, three months after President Dmitry Medvedev put it on hold pending a full inquiry.
Activists want the road to be re-routed.
Fetisov was attacked two days before Oleg Kashin, a journalist with the influential Kommersant daily, was severely beaten by two men outside his home in Moscow. Kashin, who has been voted Journalist of the Year by Russian bloggers, had also criticized the project.
