A BRAZILIAN man shot dead by armed police on Friday was innocent, police have said.

The Brazilian government has now demanded an explanation of why Jean Charles De Menezes was killed on a Tube train at Stockwell station.

British diplomats are expected to meet with officials of the South American country today.

Police called the death of the 27-year-old electrician a "tragedy" and offered their condolences to the man's family.

At least two investigations, one by the independent Police Complaints Commission, into the circumstances surrounding the shooting have been launched.

The investigation will focus on why Mr Menezes, who reportedly spoke good English, ran from plain-clothes police officers into the south London Tube station.

He had emerged from a house in Tulse Hill that was under observation as it was linked to the attempted bombings. His clothing and behaviour "added to suspicions", a Scotland Yard spokesman said.

He added: "For somebody to lose their life in such circumstances is a tragedy and one that the Metropolitan Police Service regrets."

It is thought the officer who shot Mr Menezes has not been suspended but removed from "front-line" duties.

Last night the Met said it was "satisfied" that Mr Menezes was not linked to the terror investigation of July 21.

The statement came after Met chief Sir Ian Blair said on Friday that the shooting was "directly linked to the ongoing and expanding anti-terrorist operation".

Meanwhile the hunt for the four would-be suicide bombers who failed to launch a second wave of terror attacks in the capital continues.
