Dmitry Fotyanov, 31, a mayoral candidate representing pro-presidential party United Russia, was shot on October 19 while leaving his office in Dalnegorsk, a town seven time zones east of Moscow.
Yury Melnikov said, "The investigation has brought charges of involvement in the murder of Fotyanov against three people. Two of them have been arrested and one has been put on the wanted list."
Russia has been plagued by a series of suspected contract murders recent months, most prominently a top banker and a journalist.
First Deputy Chairman of the Central Bank of Russia Andrei Kozlov, 41, who oversaw bank licensing and led efforts to close down dozens of banks for violations of banking legislation died September 14 after being shot the previous day. A Moscow court has sanctioned the arrest of three suspects in the murder case.
Anna Politkovskaya, a 48-year-old investigative journalist known for her outspoken reports on Chechnya, was gunned down in an apparent contract killing in Moscow on October 7.
