The man suspected of shooting Russian journalist Anna Politkovskaya in 2006 has been arrested in Chechnya, Russian and Chechen sources say.
Rustam Makhmudov was arrested overnight at his parents' home, his lawyer told AFP news agency.
Two of the detainee's brothers and a third man are currently awaiting trial over the murder in Moscow.
Politkovskaya's murder in cold blood outside her home in the Russian capital caused shock and revulsion.
Rustam Makhmudov's brothers, Dzhabrail and Ibragim, have been accused of acting as drivers at the scene of the crime while former police officer Sergei Khadzhikurbanov has been accused of providing logistical support.
