Operation Countryman was an investigation into police corruption that ran from 1978 – 1982  It was the fourth investigation into Metropolitan Police corruption in the seventies. The other three are briefly mentioned in this link on The Fall of Scotland Yard  . Unfortunately Countryman was another one which was derailed.
According to Steven Box, whose book extracts follow, 4 Commanders, 4 Chief Superintendents, 8 Superintendents, 15 Chief Inspectors and 6 Inspectors were suspects!  [1a]
The inquiry was carried out by men from outside forces but suffered obstruction from the Met Police. The Chief Constable of Dorset Constabulary, Arthur Hambleton alleged that Countryman had been wilfully obstructed by Commissioner McNee and Director of Public Prosecutions Sir Thomas Hetherington. Thomas Hetherington is a name that crops up also when child abuse cases are not followed through, including Peter Hayman  and Dickens delivered at least one of his dossiers to Hetherington. Spotlights links are well worth reading on this 
I have not had time to examine the FOI requests in depth on Operation Countryman on What Do They Know website . It appears as though not much information on the investigation is left. The information was passed back to the Met police, which with the City of London Police, was one of the forces being investigated and henceforth it disappeared! The Home Office though do have some boxes of information.
Other relevance to my posts on child sexual abuse is that an an analysis of legal authorities, police and customs is necessary in ascertaining what happened as regards child sexual abuse in London.  
Other posts relevant are cathy fox blog category Paedophilia around Piccadilly . The posts on police corruption  will be used in the future post on how the police corruption might have affected the child sexual abuse investigations 
I include the 1982 Granada World in Action programme on Operation Countryman  obtained by Ian Puddick, but primarily this post includes a summary of Operation Countryman from Power, Crime and Mystification by Stephen Box, as well as an analysis of Police crime.
