If this turns out to be substantiated, it really IS shocking.
Officers trailed Mr de Menezes as he boarded a bus to the Stockwell tube station.
Contrary to subsequent reports, he was not wear- ing a bulky coat or carrying a bag.
The leaked material includes photographs of Mr de Menezes' bloodstained body inside the train carriage, from which it can clearly be seen that he is wearing a close-fitting denim jacket and a light T-shirt.
And on arrival at the Underground station, he did not vault the ticket barriers — as subsequently claimed — to evade his plain-clothes pursuers.
Instead, he used his season ticket to get through the barrier, collected a free newspaper and proceeded calmly down the escalators, breaking into a run only when he saw that a train was preparing to depart.
On boarding the train, he was approached by pursuing plain-clothes police officers. One seized him while a second discharged 11 shots from a pistol at point-blank range.
A witness statement from one of the officers on the train claims that he grabbed Mr de Menezes around the body, pinioning his arms, while another officer fired at the man from a distance of about 30 centimetres.
The officer's statement, perhaps the most damaging of all for Scotland Yard, invites the conclusion that the eight bullets that hit Mr de Menezes — seven of which hit him in the head — were an overreaction to a suspect who had already been overpowered.
Metropolitan Police Commissioner Sir Ian Blair, a popular London figure who told reporters after the shooting that Mr de Menezes was challenged and refused to obey police instructions, was not available for comment yesterday.
Despite the release of closed-circuit TV footage showing the July 7 and July 21 bombing suspects, police have never released images of Mr de Menezes to support their claims that he had been wearing a bulky jacket and running from police. Scotland Yard and the Blair Government both remained silent on the revelations last night.
