Editing Great Train Robbery (1963) (section)

==Aylesbury investigation==
At 05:00, [[Chief Superintendent]] [[Malcolm Fewtrell]], head of the Buckinghamshire Police Criminal Investigation Department ([[Criminal Investigation Department|CID]]), located at [[Aylesbury]], arrived at the crime scene, where he supervised evidence-gathering. He then went to [[Cheddington railway station]], where the train had been taken, and where statements were taken from the driver and postal workers.<ref name=telegraph>{{cite news |url=https://www.telegraph.co.uk/news/obituaries/1505956/Chief-Superintendent-Malcolm-Frewtrell.html |title=Chief Superintendent Malcolm Frewtrell |newspaper=Telegraph |date=21 December 2005 |access-date=5 January 2017 |archive-url=https://web.archive.org/web/20170106105504/http://www.telegraph.co.uk/news/obituaries/1505956/Chief-Superintendent-Malcolm-Frewtrell.html |archive-date=6 January 2017 |url-status=live }}</ref> A member of the gang had told the postal staff not to move for half an hour and this suggested to the police that their hide-out could not be more than {{convert|30|mi|-1}} away.<ref name=ITV2012/> It appeared, from interviews with the witnesses, that about 15 hooded men dressed in blue boiler suits had been involved, but little more could be gleaned.

By lunchtime of the following day, it became obvious to Fewtrell that extra resources were needed to cope with the scale of the investigation and the [[Buckinghamshire]] [[Chief Constable]] referred the case to [[Scotland Yard]]. George Hatherill, Commander of the C Department and Detective Chief Superintendent Earnest (Ernie) Millen, Head of the [[Flying Squad]] were initially in charge of the London side of the investigation. They sent Detective Superintendent Gerald McArthur and Detective Sergeant John Pritchard to assist the Buckinghamshire Police.

The police then undertook a major search, fanning out from the crime scene after having failed to find any forensic evidence there. A watch was put on the seaports. The [[Postmaster General of the United Kingdom|Postmaster General]] [[Reginald Bevins]] offered a £10,000 reward to "the first person giving information leading to the apprehension and conviction of the persons responsible for the robbery".

===Discovery of Leatherslade Farm===
Following a tip-off from a herdsman who used a field adjacent to Leatherslade Farm, a police sergeant and constable called there on 13 August 1963, five days after the robbery.<ref>The Great British Train Robbery, 1963.</ref>{{page needed|date=August 2020}} The farm was deserted but they found the truck used by the robbers, which had been hastily painted yellow, as well as the Land Rovers. They also found a large quantity of food, bedding, sleeping bags, post-office sacks, registered mail packages, banknote wrappers and a [[Monopoly (game)|Monopoly board game]].

It was determined that although the farm had been cleaned for fingerprints, some finger and palm prints (presumably of the robbers) had been overlooked, including those on a ketchup bottle and on the Monopoly set (which had been used after the robbery for a game, but with real money).
