Boris Gudz, a veteran of the Soviet secret police who helped track down British spy Sydney Reilly in the early 1920s, has died aged 104.
Mr Gudz died in Moscow on Wednesday night.
Mr Gudz joined the Bolshevik OGPU secret police in 1923 and in 1925 he took part in its so-called Operation Trust aimed at luring Reilly, a top British agent, into Russia to join an anti-Bolshevik organisation which was in fact an OGPU trap.
