A second man has been arrested over Friday’s bombing of a London commuter train that injured 30 people and Britain remained on its highest level of alert on Sunday with soldiers helping provide security.
The 21-year-old man was detained under Britain’s Terrorism Act in the west London suburb of Hounslow just before midnight on Saturday, the Metropolitan Police said in a statement.
Police arrested an 18-year-old man in the departure lounge of Dover port earlier on Saturday in what they called a “significant” step and then raided a property in Sunbury, a town near London and about four miles (six km) from Hounslow.
The home-made bomb shot flames through a packed train carriage at west London’s Parsons Green Tube station during the Friday morning rush hour but apparently failed to detonate fully.
Islamic State claimed responsibility, as it has for other attacks in Britain this year, including two in London and one at a concert by American singer Ariana Grande in Manchester in May.
