Clifford Osmond (born 1908)

Clifford Osmond was head of Royal Mail’s criminal investigations authority, the Investigation Branch (IB), at time of Great Train Robbery in 1963. Osmond had lobbied for greater security on Travelling Post Offices before the robbery and the IB played a substantial role in bringing the robbers to the dock.

Following the robbery, every Investigation Branch officer was put on the case. Osmond also arranged for the Post Office to put up a reward of £10,000 which eventually helped lead to the discovery of the criminals hideout at Leatherslade Farm near Oakley in Buckinghamshire.
