The British newspaper reports that the man was the sixth person detained in connection with the investigation into the alleged plot at RAF Fairford airbase. His release on bail is the latest development reported in the case.
According to the Guardian, the suspect is a British-Iranian dual national and is 25 years old.
The arrest, the newspaper reports, took place on suspicion of preparing acts of terrorism under Section 5 of the Terrorism Act 2006. This is the allegation associated with the arrest, not a definitive finding of fact.
The material provided does not identify the man by name or include details of any attack that may have been planned.
The Guardian also reports that counterterrorism police are investigating possible involvement by a foreign state. Any role played by state actors therefore remains an investigative hypothesis.
The case remains linked to an alleged plot at RAF Fairford, while investigators continue examining the allegations against the 25-year-old and any possible foreign involvement, according to the Guardian.
