They were arrested in London and Swindon, about 80 miles west of the capital, and in Stockport and Rochdale in the northwest. The other man was arrested in the Manchester area. “All three men have been taken into custody and searches continue at the three addresses,” the police said. They added that the men were detained under the National Security Act 2023, which was introduced to tighten protections against hostile acts against Britain. Yvette Cooper, the home secretary, described the arrests as “serious events that demonstrate the ongoing requirement to adapt our response to national security threats.”
