Overview
- Police from NSW and the Australian Federal Police jointly released handwriting samples and images late Monday as part of Strike Force Yewrangara and an AFP national security probe.
- Investigators say more than 100 letters were mailed between 2015 and 2026 to state and federal parliamentarians, religious organisations and community leaders and that the material amounts to harassing or threatening behaviour.
- The correspondence carries distinctive forensic clues such as the pseudonyms 'Scorpio' and 'Bullit', prominent capitalisation of the letters F, L, T, N and H, coloured marker underlines, clippings from newspapers and apparent impressions from a bullet used as a stamp.
- Police believe the writer is a Caucasian man in his 60s, say they are 'closing in', and are urging anyone who recognises the handwriting or symbols to contact Crime Stoppers; no arrests have been announced and recipients have not been named.
- Authorities warn of a real risk of escalation and have flagged concerns about the writer's wellbeing and access to health or support services, a development that comes after several separate threats to public figures earlier in 2026 and could increase security scrutiny of targeted persons.
