Second man arrested in connection with London train blast
A second man has been arrested in connection with an explosion in a London Underground train that injured at least 29 people Friday. Police say they arrested a 21-year-old man Saturday night in west London. An 18-year-old man was also arrested Saturday, near the port of Dover on the English Channel, where he may have been trying to board a ferry to leave the U.K.
The multiple arrests indicate the blast was part of a coordinated attack rather than committed by a lone wolf. London's terror threat has been raised to "critical," indicating another threat is "expected imminently." "We are still pursing numerous lines of enquiry and at a great pace," Neil Basu, counter-terrorism coordinator of the London police, said.
