Met Police FOI — London Havana Syndrome incident, 2019

Metropolitan Police Service · 2019 / requested 2026

National security — NCND; IR upheld

Request

Reported Havana Syndrome / AHI incident in London, 2019, including whether there was liaison on the case.

Outcome

After an extension, Met Police neither confirmed nor denied under national security. Internal review came back quickly and left the NCND standing. Hume considered ICO but waited on a parallel DSTL request. The i newspaper had reported MI6 and DSTL filling a JASON/MITRE-like function.

UK police NCND on a domestic AHI report — Hume's domestic counterpart to the DSTL paper.

    I foia'd the Met police and after an extension they ruled as NCND under NatSec.
