LONDON — Britain lowered its security threat level from “critical” to “severe” Sunday after the arrests of two suspects in the terrorist attack on the London underground railway.
Police have made “good progress” in the investigation, Home Secretary Amber Rudd said. The new threat level still indicated that another attack was highly likely and that people should continue to be “vigilant.”
London’s Metropolitan Police said in a statement that the second terrorism suspect, a 21-year-old man, was arrested in west London late Saturday night.
Police have also detained an 18-year-old in the port city of Dover suspected of links to the bombing. Media reported that the suspect lived with foster parents in the town of Surrey near London, and that the elderly couple had fostered a number of children and youths in the same house.
