Three people have been arrested in Essex as part of a Counter Terrorism Policing Investigation into suspected National Security Act offences, which is being led by the Met's Counter Terrorism Command. A 41-year-old man [A] and a 35-year-old woman [B] were arrested at an address in Grays, Essex. All three were arrested on Wednesday, 17 September on suspicion of assisting a foreign intelligence service, contrary to section 3 of the National Security Act (NSA), 2023 and they were taken to a police station in London. Commander Dominic Murphy, Head of the Counter Terrorism Command, said: "Through our recent national security casework, we're seeing an increasing number of who we would describe as 'proxies' being recruited by foreign intelligence services. "But anyone who might be contacted by and tempted into carrying out criminal activity on behalf of a foreign state here in the UK should think again.
