Section D — Circumstances of Disappearance / Intelligence Background
Narrative — include all known relevant facts
Summary of Circumstances
Subject came to the attention of Special Branch, Section D, in the context of Operation Blackwood, following the theft of classified materials from the ████████████████████ Collection in October 1923 and the subsequent unaccounted departure of two senior archivists, both of whose whereabouts remain unknown.
Subject is the primary intelligence interest in this matter. Eleven months of surveillance, commencing January 1923, produced three confirmed intercepts and two field contacts — the latter now deceased. Subject is believed to be in possession of a document referred to internally as the ████████████████████████████, the contents of which constitute a matter of significant national security interest.
Subject is not believed to be operating alone. Associates, if any, are unidentified.
Section E — Risk Assessment
Completed by reporting officer in consultation with Section D
Risk Grade
HIGH
Grounds for Risk Grade
Subject is believed to be in possession of documents of active national security interest. Subject may be aware of surveillance and may take steps to evade detection. Communications with foreign intelligence networks are suspected. Subject is not considered a danger to the general public, but any approach must be treated with extreme care.
Authorised Action
OBSERVE AND REPORT ONLY. Do NOT detain, approach, or make contact without prior written authorisation from the Commander, Section D, Special Branch. Any attempt to make contact must be pre-sanctioned and recorded. Failure to observe this instruction may compromise the active operation and will be treated as a disciplinary matter.
