PhotoLONDON — The man who detonated explosives at a pop concert in Manchester, England, last week, killing 22 people and wounding dozens, mainly acted alone in the days leading up to the attack, the British police said late Tuesday. The sophisticated planning and execution of the attack had initially led the British authorities to believe that the assailant, Salman Abedi, had the support of a larger terrorist cell. That, in turn, led to fears that a bomb maker and a network of people who provided support could still be at large, and even preparing further attacks. To date, 16 people have been arrested in connection with the attack, though five of those have been released without charges. “We will be seeking to extend the custody of some of them as we work to understand what has gone on and whether Abedi was helped.”
