LONDON — The Latest on the London subway attack and manhunt for suspects (all times local):
British police have made an apparent breakthrough in subway bombing investigation with what they are calling a “very significant” arrest, but the country remains on a “critical” alert, meaning that another attack is judged imminent.
Police arrested an 18-year-old man in the port of Dover — the main ferry link to France — and then launched a massive armed search in the southwestern London suburb of Sunbury. Residents said they were evacuated immediately as police established a huge cordon and imposed a no-fly zone above the property being searched.
Home Secretary Amber Rudd and others said the arrest was of major importance.
The man is being held under the Terrorism Act and has been brought to London for questioning. His identity is a closely guarded secret and police have implored the press not to speculate while the inquiry unfolds.
British Home Secretary Amber Rudd says it is “much too early” to tell if authorities knew of the suspect in the London subway bombing
Rudd said Saturday it was “good fortune” that the bomb on the District Line train did not do more damage. She said it was a “serious” improvised explosive device that could have caused much more harm.
She says the arrest Saturday of an 18-year-old suspect was “very significant” and that police are making rapid progress in the investigation. Rudd said the independent Joint Terrorism Analysis Center will gauge whether to keep the country’s terrorist threat level at “critical” in the coming days.
Rudd said she has briefed Prime Minister Theresa May on developments in the attack Friday that left 29 people injured.
British police say that armed officers are searching a home in a London suburb and evacuating neighbors as a precaution as part of the investigation into the subway blast.
Police say the operation is taking place in Sunbury, an area on the southwestern outskirts of the capital and about five miles (eight kilometers) from London’s Heathrow Airport.
Police said cordons were put in place around the neighborhood to clear the area for police.
Police earlier Saturday arrested a suspect in the port of Dover and are hoping to gather information from the suspect in custody. Police said no further arrests have been made.
A bomb partially exploded aboard a London subway train during the Friday morning rush hour, and 29 people were left injured.
