HC Deb 28 February 1940 vol 357 c2043
12. Mr. Dolan

asked the Secretary of State for Air whether he will issue orders to all concerned who are in charge of confidential documents not to leave these in unattended motor-cars, as nearly a dozen cases of theft of these valuable secret documents have been reported since the beginning of the war?

Captain Balfour

Instructions on this matter have already been issued. So far as I am aware, there has been no case since the outbreak of war in which the staff of my Department have been involved.
