British Authorities Detain Iranian Suspects in Terrorism Probe
Eight men, including seven Iranians, have been arrested by UK counterterrorism units during ongoing investigations into potential plots.
On Sunday, May 4, 2025, British counterterrorism forces apprehended eight individuals, notably seven Iranian nationals, amid two separate inquiries, as stated by London’s Metropolitan Police. In one of the cases, four of the Iranians and an additional man of unknown nationality were arrested on suspicion of plotting a terrorist attack against a specific location, described by police as undisclosed “for operational reasons.”
Dominic Murphy, head of the Metropolitan Police’s Counter Terrorism Command, characterized the investigation as “fast-moving,” mentioning that police were collaborating closely with the entity potentially impacted by the plot in order to keep them informed. He further indicated that the inquiry is still in preliminary stages, with law enforcement exploring various motives and assessing any potential danger to the public.
The police detailed the ages of the detained Iranian nationals: two were 29, one was 46, and the other was 40. Their arrests took place in locations including London, Swindon—approximately 80 miles from the capital—Stockport, and Rochdale. Another suspect was captured in Manchester.
In a subsequent note, authorities disclosed that three other Iranian nationals—aged 39, 44, and 55—were taken into custody in different parts of London on the same day; however, these arrests were deemed unrelated to the initial investigation. All three men are being held under the National Security Act 2023, which aims to fortify the country against foreign threats.
Home Secretary Yvette Cooper labeled these arrests as "serious events" that highlight the ongoing need for a responsive national security approach. She affirmed the government’s commitment to cooperating with police and intelligence agencies to manage necessary security actions.
Though particulars regarding the investigations remain scarce, Ken McCallum, head of MI5, previously highlighted Iran as an escalating threat to national security, noting that British authorities have addressed 20 plots allegedly backed by Iran since January 2022, which posed serious risks to local citizens. He pointed to a recent conviction of an individual for reconnaissance activities targeting the headquarters of Iran International, a prominent Persian-language opposition media outlet operating in the UK.
Health Secretary Wes Streeting, when approached about the incidents, stated that the government would keep the public informed but refrained from providing further comments given the sensitive nature of ongoing investigations.
