SUNBURY, SURREY, ENGLAND, UNITED KINGDOM (SEPTEMBER 16, 2017) (BBC) – British police arrested an 18-year-old man in the port of Dover and raided a house in a small town outside London on Saturday (September 16) as they hunted for whoever planted a bomb on a commuter train that injured 30 people a day earlier.
In what authorities called a “very significant” development, officers arrested a man at about 7.50 a.m. (0650 GMT) in Dover, from where passenger ferries sail to France. Five hours later they raided a property in Sunbury, a commuter town southwest of London, and evacuated nearby premises as a precaution.
Video showed police cordons in a modest suburban street in Sunbury, in the county of Surrey, around 11 miles (18 km) from Parsons Green where the bomb exploded.
Prime Minister Theresa May put Britain on the highest security level of “critical” late on Friday (September 15), meaning another attack may be imminent, and deployed soldiers and armed police to strategic locations.
