Brian Paddick will not face disciplinary action over an alleged unauthorised disclosure of confidential police information to a journalist.

The Metropolitan Police Authority (MPA) had been considering a probe into the Deputy Assistant Commissioner’s actions after he was reported to have told a BBC journalist that the Metropolitan Police knew Jean Charles de Menezes was an innocent man just six hours after he was shot at Stockwell tube station in 2005.

He allegedly told the reporter he had made a statement to the Independent Police Complaints Commission (IPCC) which said a senior member of the head of the Met’s office believed the wrong man had been targeted just six hours after Mr Menezes was killed because he was a suspected suicide bomber.

The MPA met last night after a member of the force had complained about the comments.

The authority said in a statement, “The sub-committee noted that the senior officer had recognised that with the benefit of hindsight his conversation with the journalist was unwise and something he would not repeat.

“They decided that in all the circumstances not to pursue disciplinary action. The outcome will be reported back to the Independent Police Complaints Commission.

“The senior officer has been made aware of the sub-committee’s conclusions and the matter is now closed.”

Meanwhile Mr Paddick, the Met’s most senior gay police officer, is rumoured to have been interested in standing as a Liberal Democrat candidate for London Mayor in 2008.
