A leaked police investigation report into the killing of Brazilian Jean Charles de Menezes is taking curious twists and seems to be coughing up more questions than answers.

It’s already been noted that the initial witness statements suggesting Mr Menezes vaulted the ticket barrier to get into the station may have been incorrect and that the witness actually saw a pursuing police officer vaulting the barriers.

Witness statements and photographs from an independent police investigation leaked to ITV News also show that Jean Charles de Menezes did not run away from police at Stockwell Tube station in South London and was wearing only a denim jacket before he was shot dead on July 22.

Then, it seems, the officer watching Menezes’ flat was taking a leak when Menezes left and nobody checked to see whether the man they were following resembled the alleged bomber they were keeping under surveillance.

Gold Command at the Yard which was running this operation, declared a “code red” and handed responsibility to CO19 - the firearms team. The armed team had been given photographs of the alleged bombers, yet no one realised that Senhor de Menezes bore no resemblance to any of those men.

The photo (right) shows Menezes to not be wearing the thick coat that was originally claimed but, instead, a denim jacket. Further, new witness statements suggest Mr Menezes was actually sitting down by the time police reached his carriage.

…a surveillance officer guided four armed police into the same carriage in which Senhor de Menezes took his seat.

A man sitting opposite him is quoted as saying: “Within a few seconds I saw a man coming into the double doors to my left. He was pointing a small black handgun towards a person sitting opposite me.

“He pointed the gun at the right hand side of the man’s head. The gun was within 12 inches of the man’s head when the first shot was fired.”

The report also reveals for the first time that a member of the surveillance team, who sat nearby, got involved and grabbed Senhor de Menezes before he was shot: “I heard shouting which included the word ‘police’ and turned to face the male in the denim jacket.

“He immediately stood up and advanced towards me and the CO19 officers …I grabbed the male in the denim jacket by wrapping both my arms around his torso, pinning his arms to his side.

“I then pushed him back onto the seat where he had been previously sitting … I then heard a gun shot very close to my left ear and was dragged away onto the floor of the carriage.”

Somebody has to quickly round up the facts of this matter and put them into the open because it’s all smelling pretty rotten. What started off as a hideous mistake (in most people’s eyes) is now becoming something even more sinister. If the police are to maintain credibility we need to hear the truth - however bad it is - rather than leaked snippets that contradict the currently understood version of events. We need confidence in our security services and this isn’t fostering much of it.
