Burton factory worker Munir Mohammed used an extremist video to learn how to build a bomb – and that film was still available online only last week, despite his plot being foiled 13 months ago, it is claimed. David Ibsen, executive director of the Counter Extremism Project, which helps to draw up legislation to combat online extremism, said: "The availability of [the bomb making] video is deeply concerning to the Counter Extremism Project (CEP) and the general public. "We believe that this ISIS bombing making video is the one Munir Mohammed downloaded in November 2016 when planning an attack."
