Third arrest made in London subway attack, police say
British police have arrested a third suspect in connection with the bomb that partially exploded on a London subway last week.
Police said they arrested a 25-year-old man in Wales on Tuesday evening under the Terrorism Act. They say a property in Newport, Wales, 140 miles west of London, was being searched.
Two other men arrested over the weekend — an 18-year-old refugee from Iraq and a 21-year-old from Syria — remain in custody. Neither has been charged. London police have not released details from the investigation.
Cmdr. Dean Haydon, head of the Metropolitan Police Counter-Terrorism Command, said searches were underway at four locations, including three that had been in progress before Tuesday.
The searches may take “some days to complete” as detectives seek to determine the “full facts” behind the attack, Haydon said.
The homemade explosive device, which had been placed in a bucket that was enclosed by a shopping bag, injured 30 people when it partially detonated in a crowded subway car on Friday morning around 8:20.
The District Line train was carrying commuters, including many schoolchildren from the suburbs. Photographs on social media of the charred white plastic bucket showed wires protruding from the top. The device was similar to a bomb used in a suicide attack in Manchester in May that killed 22 people, authorities said.
The subway was stopped at the Parsons Green station when the device went off. The attack prompted Prime Minister Theresa May to put the country on high alert.
Home Secretary Amber Rudd said the rush-hour explosion would have caused many more injuries if it had fully detonated.
Britain’s official terrorist threat level was raised to “critical” after the attack — meaning an attack was judged to be imminent — but it was lowered after the first two arrests.
Those suspects are believed to have at one point lived in a foster home in Sunbury, a suburb southwest of London. Details about the third suspect have not yet emerged.
Islamic State extremists have claimed responsibility, but British officials have said they don’t see proof of a connection yet.
The attack was the fifth in Britain this year.
