A man shot dead by police hunting the bombers behind Thursday's London attacks was unconnected to the incidents, police have confirmed.
The man was killed in Stockwell Tube station in an incident described by Scotland Yard as a "tragedy".
A Scotland Yard statement read: "We believe we now know the identity of the man shot at Stockwell Underground station by police on Friday 22nd July 2005, although he is still subject to formal identification.
"We are now satisfied that he was not connected with the incidents of Thursday 21st July 2005.
"For somebody to lose their life in such circumstances is a tragedy and one that the Metropolitan Police Service regrets."
The statement confirmed the man had been followed by police from a house in Tulse Hill that was under surveillance.
His death is being investigated by officers from the MPS Directorate of Professional Standards, and will be referred to the Independent Police Complaints Commission.
John O'Connor, former commander of the Met Police, told the BBC the consequences of the shooting were likely to be "quite horrendous".
He said he expected officers to face criminal charges, and other officers could even refuse to carry weapons.
