Mohammed Beck Hadjetlaché (20 May 1868, Istanbul - 4 November 1929, Stockholm) was a Circassian journalist, writer, MI6 (SIS) agent, and anti-communist white movement terrorist.
[1] In 1916 Hadjetlaché offered to run an "anti-German and anti-Turkish propaganda campaign among the Moslems on a worldwide scale" for the Russian government and asked for money.
[3] He left Soviet Russia and went to Sweden in 1918, where he organized a White Terrorist cell called the "Russian League", which planned to help in the counter revolutionary struggle against the Bolsheviks with Stockholm as its base.
The confirmed victims were engineer Karl Calvé (originally possibly Gleb Varfolomeyev), journalist and Soviet diplomatic courier Juri Levi (Paul) Levitsky and nobleman Nicolai Ardachev, a doctor in law.
Hadjetlaché was sentenced to death on 28 May 1920 by guillotine, later converted to life in accordance with the de facto moratorium persisting before abolition the next year.
