Counter-terrorism police in London arrested a 22-year-old British national in Westminster on suspicion of preparation of terrorist acts under section 5 of the Terrorism Act 2006. The arrest forms part of an investigation into threats to RAF Fairford, a Royal Air Force base in Gloucestershire. This marks the seventh arrest made in connection with the case, according to counter-terrorism police.

The suspect faces formal charges under anti-terrorism legislation that relates specifically to the preparation of terrorist acts. Counter-terrorism officers did not disclose further details about the nature of the alleged threats to the military installation or the scope of the broader investigation.

RAF Fairford hosts US Air Force B-52 bombers and serves as a key NATO base. The base has been a target of security concerns in the past, though the source material does not detail what prompted the current investigation or when the alleged threats were made.
