The UK arrested a second suspect in connection with the blast on a commuter train as London’s counter-terrorism police widened their investigation into the attack that
injured at least 30 people. The UK threat level remained
at critical.
Police arrested a 21-year-old man in Hounslow, southwest London, late Saturday, the Metropolitan Police said in a statement. He was being held under the UK Terrorism Act in a south London police station. Police on Saturday morning arrested an 18-year-old man in the departure area of the port at Dover, the main ferry link between the UK. and France that saw over 12 million passengers in 2016.
Prior to the second arrest, officers had evacuated residents in a section of Sunbury-on-Thames in Surrey, about 24 kilometres southwest of London, as they searched a home as “a precautionary measure” after the arrest, according to a statement.
That search “will take some time,” Neil Basu, the Metropolitan Police’s senior national coordinator for counter terrorism policy, said. “We are keeping an open mind around whether more than one person is responsible for the attack and we are still pursuing numerous lines of inquiry and at a great pace.”
Police have identified 121 witnesses to the attack at the Parsons Green station.
