Officer had raised concerns in month before attack that ‘something could get through’ due to high workload
MI5 had enough intelligence to regard Salman Abedi as a threat to national security and open an investigation before he bombed the Manchester Arena, killing 22 people and injuring hundreds of others, an inquiry has heard.
The Security Service was “struggling to cope” with an increased workload, and the team responsible for the north-west of England had declared an “amber” period of stress and high capacity the month before the attack in 2017.
