British officials have lowered the country’s official terrorist threat level from “critical” to “severe” following the arrest of a second man in the London subway bombing.
Home Secretary Amber Rudd said Sunday that this is an indication that “good progress” is being made into the investigation of the Friday attack on a London subway train that injured 30 people. She cautioned that it is still an ongoing investigation.
The “severe” threat level now in place means officials believe another attack is highly likely. When it was set at “critical,” that meant authorities judged an attack to be imminent.
The threat level is set by the Joint Terrorism Analysis Center.
Britain’s National Health Service says all but one of the people wounded in the subway bombing attack have been released from the hospital.
The health service said Sunday that one person is still being treated at Chelsea and Westminster Hospital, which has a special unit for treating burns.
Officials raised the total number of people injured Friday by the partial detonation of a bomb on the subway train and the stampede that followed to 30. That includes 19 people taken from the explosion site to hospitals and 11 others who came in for treatment on their own.
Many of the injuries were reported to be burns.
British police are searching a home in the London suburb of Stanwell linked to the arrest of the second suspect in the subway bombing.
Police said Sunday the search is connected to the arrest late Saturday of a 21-year-old man taken into custody under the Terrorism Act. He is the second man arrested on suspicion of being involved in Friday’s attack on a London subway train that injured 30 people.
Stanwell is about 15 miles (25 kilometers) southwest of central London, heading toward Heathrow Airport.
Police had earlier searched a house in Sunbury believed to be linked to the first suspect, who was arrested at the Dover ferry port.
