UK police arrest 2nd man in London subway attack case

LONDON – London police say a second man has been arrested in connection with the London subway attack.

Police said Sunday that a 21-year-old man was arrested late Saturday night in Hounslow in west London and is being held under the Terrorism Act. He is being questioned at a south London police station but has not been charged or identified.

Two men are now in custody for possible roles in the bombing attack on a rush-hour subway train Friday morning that injured 29 people in London. An 18-year-old man was arrested Saturday in the departure area of the port of Dover, where ferries leave for France.

The two arrests indicate police and security services believe the attack at the Parsons Green station was part of a coordinated plot, not the act of a single person.
