An investigation has begun after a senior officer admitted changing evidence during the inquest into the death of Jean Charles de Menezes.
The Special Branch officer, named as Owen, said he deleted a line from computer notes which quoted Deputy Assistant Commissioner Cressida Dick.
The surveillance officer told the inquest the deleted line claimed Ms Dick had initially said the electrician could "run onto Tube as not carrying anything".
But on Monday he said: "On reflection, I looked at that and thought I cannot actually say that."
I await the transcript with interest.
