Manchester Arena bombing ‘might have been prevented’, inquiry finds

The Manchester Arena terror attack might have been prevented if MI5 had acted on key intelligence received in the months before the attack, an inquiry has found. Two pieces of information about suicide bomber Salman Abedi were assessed at the time by the security service to not relate to terrorism. But inquiry chairman Sir John Saunders said having heard from MI5 witnesses at the hearings into the May 2017 atrocity – that killed 22 people and injured hundreds – he considered that did not present an “accurate picture”. Tne officer admitted they considered a possible pressing national security concern on one of the pieces of intelligence but did not discuss it with colleagues straightaway and did not write up a report on the same day.
