A 25-year-old dual UK-Iranian national arrested in connection with a suspected terrorist plot at RAF Fairford has been released on bail, according to The Guardian.

The man was detained on suspicion of preparing terrorist acts under section 5 of the Terrorism Act 2006. He is the sixth person arrested as counter-terrorism police investigate what they describe as a "possible foreign state involvement" in the alleged plot.

RAF Fairford is a major Royal Air Force base in Gloucestershire that hosts US Air Force operations. The details of the specific allegations against the arrested individuals remain limited in the public record at this stage of the investigation.

Counter-terrorism officers have not yet disclosed what prompted the investigation or what specific target or method the alleged plot may have involved. The release on bail suggests investigators require further time to build their case while the suspect remains subject to conditions.

The investigation represents an active counter-terrorism operation. No charges have been filed as of the report date.
