This is an excerpt from the 'Matt Rayner' profile at the former Undercover Research Group wiki, last updated in 2019.
Denise Fuller, the woman who was deceived into a relationship by HN1, gave evidence in 2024, and HN1 himself appeared in 2025. An updated profile will appear in due course.
HN1 'Matt Rayner' was an undercover police officer with the Special Demonstration Squad. He infiltrated the animal rights movement in north London from 1991 to 1996, targeting in particular the London Boots Action Group, London Animal Action, Animal Liberation Front and West London Hunt Saboteurs.
He had a sexual relationship with Denise Fuller while deployed; she gave evidence at the Inquiry.
Rayner was one of two undercovers in animal rights in the early 1990s, and who were referred to indirectly in Rob Evans & Paul Lewis' book Undercover.
