On 17 November police investigating the Liverpool taxi explosion sent a bomb disposal vehicle and fire engine to Sutcliff Street and extended a cordon around the Kensington area of Liverpool to allow them to assess ‘materials’ found during their search on the asylum accommodation. Residents living within the cordon were told they were not able to return home, while investigators continue to work on piecing together a motive for the blast. Apparently, Emad al-Swealmeen had been buying parts for his homemade device since at least April. Meanwhile, David Perry, who reportedly averted disaster by locking the bomber in his vehicle is said to have spoken to counter-terrorism officers for 90 minutes at his home. Priti Patel said the asylum system is ‘dysfunctional’. Patrols by armed police will be increased and security plans for major events reviewed after the terror threat level was raised following the attack.
