(BBC) The Manchester Arena suicide bomber was missed by seconds by a police patrol, the inquiry into the bombing heard.
Salman Abedi, dressed in black and bent over by the weight of the home-made bomb in a large rucksack, later made his way to the foyer where he detonated the explosive, killing 22 people.
The inquiry has heard of “missed opportunities” prior to the attack.
Police personnel patrolling Manchester Arena were also absent from patrol for more than two hours, the inquiry heard.
Four British Transport Police (BTP) operatives were present on the night of the attack, one PC and three PCSOs, patrolling in pairs, the hearing in Manchester was told.
