Even cops believed in Loch Ness' existence in the 1930s

London, April 27 (ANI): A top police officer believed the existence of a Loch Ness monster was 'beyond doubt', according to a historical document.

In 1938, the chief constable of Inverness-shire raised concerns about protecting 'Nessie' from hunters, reports the Independent.

In a letter he wrote: "That there is some strange creature in Loch Ness seems now beyond doubt, but that the police have any power to protect it is very doubtful."

The document has been released by the National Archives of Scotland (NAS) as part of an exhibition An Open Secret.

The letter from William Fraser to the Under Secretary of State at the Scottish Office, describes a London couple, Peter Kent and Marion Stirling, who were "determined to catch the monster dead or alive".

The document goes on to describe how the party claimed they were having a special harpoon gun made and would return with 20 "experienced men" to track the monster down. (ANI)
