Counter-terrorism police have arrested a 22-year-old British national in Westminster, London, in connection with an ongoing investigation surrounding RAF Fairford. The individual is being held on suspicion of the preparation of terrorist acts under section 5 of the Terrorism Act 2006.

This arrest follows an incident on September 27, when police were alerted to suspicious vehicles near the RAF base in the village of Whelford, Gloucestershire. During that initial event, five men in their 20s were arrested; they have since been released on bail. While the BBC and Sky News have reported the event as a general 'incident,' The Guardian has provided specific details regarding the legal grounds for the arrest and the location of the suspect's apprehension in central London.

The investigation remains active, with authorities continuing to examine the circumstances surrounding the activity near the military site. There is currently no public information detailing the specific nature of the threat or the relationship between the seven individuals arrested throughout the course of the investigation.
