Jean Charles de Menezes was shot dead on a Tube train at Stockwell

Investigators say they are standing by their original decision not to recommend disciplining the officers who fatally shot Jean Charles de Menezes.

The Independent Police Complaints Commission (IPCC) reviewed its earlier findings after requests from the 27-year-old Brazilian's family.

The review followed the recording of an open verdict at last year's inquest into the 2005 shooting in south London.

Police had mistaken the electrician for a suicide bomber.

Reacting to the decision, a spokeswoman for the Justice4Jean campaign said it made a "mockery of the inquest's findings".

She said: "Today's decision by the IPCC... gives a green light to police officers to act with impunity.

"The family are not surprised but crushed that the IPCC have ignored the narrative verdict the jury gave at Jean Charles' inquest."

'Family crushed'

An IPCC spokesman said: "In making this decision, the IPCC has carefully considered the family's representations, the evidence identified by its own investigation and all subsequent legal proceedings."

Mr de Menezes was shot on 22 June, 2005 at Stockwell Tube station by Scotland Yard firearms officers who mistook him for failed suicide bomber Hussain Osman.

Police had been hunting Osman for trying to bomb a Tube train the day before Mr de Menezes was shot.

It came two weeks after the suicide bomb attacks on London's transport network on 7 July 2005, which killed 52 people and injured hundreds.

The death of Mr de Menezes triggered a number of inquiries that scrutinised police tactics, supervision and individual decisions.

The jury at the three-month, multimillion-pound inquest, which ended in December, rejected the police account of the shooting and returned an open verdict.

Among those who have been considered for disciplinary action are the two marksmen who pulled the trigger and senior officers behind the operation.

They include Cressida Dick, now an assistant commissioner and Scotland Yard's most senior woman officer.

The most obvious shortcomings highlighted at the inquest were the failure to correctly identify Mr de Menezes, ineffective communication and poor tactical decisions.

Officers who ran on to the Tube were also accused of falsely claiming to have yelled "armed police".

The de Menezes family has tried to pursue perjury charges against those officers and have also campaigned for a permanent memorial at the station.

An agreement is expected later this year between the family and police over compensation.
