an hour before the concert ended, whilst the audience were still inside the arena, here is abedi walking in. he goes straight to the stairs and up to a hiding place he had checked out before, out of sight on this balcony in a cctv blind spot. the enquiry heard that members of the public did notice him. i thought, suicide bomber, straightaway. with very little doubt in my mind. honestly, my heart was racing. but only one of them, a dad collecting his daughter stopped to challenge abedi. i asked him what he was doing there and did he know how bad it looks him sitting there out of sight of everybody? first, he said he was waiting for somebody and then he just kept asking after everything i said, he just kept asking what the time was.
