UK police keeping open mind on number of suspects in London train bombing

British police are keeping an open mind on whether more than one person was responsible for a London train bombing that injured 30 people, after they arrested an 18-year-old man earlier on Saturday.

“We are still pursuing numerous lines of enquiry, and at great pace,” Senior National Co-ordinator for Counter Terrorism Policing Neil Basu told reporters. “Our priorities are … to identify and locate any other potential suspects.”
