The investigation into three vans on a Cotswolds lane has moved 100 miles east. Counter terrorism officers arrested a 25 year old man in Westminster, London, on Thursday, on suspicion of preparation of terrorist acts, in what is the first time the inquiry into the suspicious activity near RAF Fairford has reached the capital. Two properties in the area were searched.
Police first gave the man's age as 27 and said a second man had been questioned under caution. Both details were withdrawn in a later update the same day.
Vicki Evans, the senior national coordinator for counter terrorism policing, said the investigation was hugely complex and that specialist teams were interrogating multiple lines of enquiry. Asked directly about state involvement, she said officers were looking at all possible angles, including possible foreign state involvement, and thanked the public for its patience.
That is six people now connected to the case. Five men in their twenties, all British nationals from London, four living in Westminster and one in Camden, were arrested in the early hours of Sunday after a resident reported three suspicious vehicles travelling toward the base. They remain on police bail and have not been charged. Their release on Monday drew criticism from President Trump.
The claim made in Washington
Within hours of the Westminster arrest, Benjamin Netanyahu said Britain had been warned. Speaking to Fox News late on Wednesday, the Israeli prime minister said Israel gave British intelligence that there was going to be an attack, and that it was an Iranian sponsored attack. He placed that warning immediately before 8 September, when the Burnham government joined eleven other nations in announcing sanctions on products from Israeli settlements in the occupied West Bank.
The prime minister, Andy Burnham, said on Wednesday that there were strong indications that Iran played a part in the incident. He gave no further detail. Tehran has strongly denied any involvement.
Secretary of State Marco Rubio said on Monday that the hands of a foreign actor had clearly been involved, without offering evidence. On Thursday, the British ambassador to Iran met the country's foreign ministry at Tehran's request, a courtesy that suggests the government regards the case as having a foreign policy dimension rather than a purely domestic one.
What has actually been found
The physical case remains thin, and police have been careful to say so. Officers said a quantity of petrol but no explosive devices were found when vans near the site were searched. Men arrived in three vehicles in the dead of night carrying large plastic drums, many of which appeared empty from aerial video, and a quantity of gasoline. The BBC reported that one of the five men dialled 999 himself roughly an hour before a local farmer alerted police to a large group of masked people near the vehicles.
On Monday, police said the men could have been, in the words of a spokesperson, either knowingly or unknowingly working on behalf of a foreign state. That formulation is doing a great deal of work. It covers every explanation from direct Iranian command to men who believed they were doing something else entirely.
What has changed in 72 hours is not the forensic picture. It is the diplomatic one. A case that began as five British men with petrol and empty drums has acquired an arrest in Westminster, a prime minister asserting that Britain was warned in advance and ignored the warning, and a foreign ministry in Tehran asking to see the British ambassador.
None of that is evidence. All of it raises the cost of the four governments involved being wrong about what happened on a lane in Gloucestershire.
