A Moscow Court has sanctioned a two-month arrest of the mayor of Dagestan's capital Makhachkala, Said Amirov, who was detained on suspicion of having organized a murder of a Russian investigator.

      According to Investigative Committee spokesman Vladimir Markin, a criminal case against Amirov in connection with the December 2011 killing of investigator Arsen Gadzhibekov in Dagestan’s Kaspiysk was opened on Friday. The official charges will be brought against him within ten days.

      Gadzhibekov, chief of the investigation department of Makhachkala's Sovetsky District, was shot dead near his house in Russia’s North Caucasus republic of Dagestan as he was leaving his car. He had participated in solving a number of crimes, including the 2010 terror attack in Kizlyar, that killed 10 and injured 270 others.

      On Friday, May 31, Dagestan police arrested a gunman and a direct executor of the murder, who told investigators about his links to the mayor.

      Amirov, 59, a long-term member of the ruling United Russia party, won the title of Russia’s best mayor at a contest in late April, Makhachkala’s administration’s site said.
