ATHENS (REUTER) - The body of a Russian man wanted in Moscow for the murder of four policemen has been recovered by Greek authorities in a joint operation with Russian security officers, police said on Tuesday. Police officials said Alexander Solonik, a former KGB officer and a suspected contract killer, was found strangled on Sunday at the northern Athens suburb of Varibobi. Solonik, 37, was wanted in Russia for allegedly killing four police officers in Moscow and injuring another, the officials said. He had been arrested in 1993 on rape charges but escaped from a Moscow prison. It was not known when he arrived in Greece. Four Russian state security officers arrived in Athens on Saturday to search for Solonik and found his body in a joint search with Greek police. A state coroner said Solonik was murdered on Saturday and his body was found in a field, wrapped in garbage bags. Police said Solonik was running a Russian mafia gang in Greece and was planning to travel to Italy this week.
