(BBC) The most senior police officer on duty before the Manchester Arena attack had taken an “unacceptable” two-hour break before the bombing, the inquiry heard.
PC Jessica Bullough admitted she then missed bomber Salman Abedi walking from the train station into the arena.
The British Transport Police (BTP) officer had been qualified for only eight months, and was still in her probationary period.
The suicide bombing killed 22 people and injured many more on 22 May 2017.
The public inquiry into the attack heard there were no police officers on patrol when 22-year-old Abedi made his journey from Victoria Station to the arena foyer.
