TIMELINE: The shooting of Jean Charles de Menezes

(Reuters) - London's Metropolitan Police was found guilty on Thursday of putting the public at risk over the killing of an innocent Brazilian mistaken for a suicide bomber.

Jean Charles de Menezes was shot dead on July 22, 2005 by armed police at an underground station in south London after being mistaken for one of four men who had tried to carry out suicide bombings on London's transport system the day before.

Here is a chronology of the main details of the incident.

July 7, 2005: Four young British Islamists carry out suicide bomb attacks on three underground trains and a bus in London, killing 52 people.

July 21: In another attempt to attack London's transport system, homemade bombs fail to explode and the four bombers flee. Police launch the country's biggest ever manhunt.

July 22: De Menezes leaves his home in south London, setting off for work. He boards an underground train at Stockwell station, where armed police pursuing him push him to the floor of the carriage and shoot him eight times, killing him.

July 23: Police issue a statement saying the man they shot was not connected to the July 21 attacks. They later identify him as de Menezes.

July 17, 2006: The Crown Prosecution Service says no officers involved in the shooting will face criminal charges, but London's police will be prosecuted under health and safety laws.

February 19, 2007: Cressida Dick, the officer in charge of the July 22 operation, is promoted to the rank of Deputy Assistant Commissioner.

May 11: The Independent Police Complaints Commission (IPCC) says officers involved in the shooting will not face disciplinary hearings and no decision has been taken regarding four commanders and tactical advisers.

August 2: An IPCC report clears London police chief Ian Blair of lying about the shooting, but says Assistant Commissioner Andy Hayman, Britain's most senior counter-terrorism officer, did mislead the public and senior figures at the Metropolitan Police.

Oct 1: Trial of Metropolitan Police Service (MPS) on health and safety charges begins.

Nov 1: Jury finds the MPS guilty of endangering the public but clears operation leader Cressida Dick of personal responsibility. The court fines the MPS 175,000 pounds ($364,000) and orders it to pay legal costs of 385,000 pounds.
