Two senior Brazilian officials have arrived in London to clarify issues relating to the killing of Jean Charles de Menezes, who was mistaken for a suspected suicide bomber.
Police shot the 27-year-old at a London underground tube station a day after the attempted bomb attack on the city's transport network on 21 July.
The Metropolitan Police Commissioner, Sir Ian Blair, yesterday said he was not aware of the Brazilian man's innocence until 24 hours after the shooting.
