Episode 4

Police believe they’ve shot one of the would-be 21 July bombers on a tube train. But was he a terrorist or was he an innocent bystander? Witnesses say he leapt the ticket barriers, running away from police

At the scene, the dead man’s personal effects suggest he’s a Brazilian called Jean Charles de Menezes and not the bomber. Nobody tells commissioner Sir Ian Blair, who holds a press conference indicating they’d shot the right man.

A tip-off leads police to the bomb factory, but the bombers aren’t there. When they finally locate a suspect, he outwits them. A desperate manhunt culminates in two armed encounters between police and the terrorists.

Two decades on, investigators, rescuers, survivors and grieving relatives reveal how the London bombings have shaped their lives.
