Sergei Mikhailov (Russian: Серге́й Анатольевич Михайлов), born 1958, nickname Mikhas, is a Russian businessman and leader of the Solntsevskaya Bratva. Mikhailov was originally a waiter, but moved into the criminal world after a conviction for fraud. Together with Viktor Averin, Mikhas formed the Solntsevo group in the late 1980s. In 1998, Mikhas was arrested in Switzerland on charges of false documents and a law about foreigners owning property. He was later acquitted and allowed to walk free from the court after spending two years in jail waiting for the trial. One of the witnesses was shot dead in Amsterdam.
