Senior Muslim officer to face new charges.
Metropolitan Police Commander Ali Dizaei, 47, is accused of misconduct in public office and perverting the course of justice.
Dizaei, president of the National Black Police Association, has been suspended from the force since September. He attended Bishopsgate police station yesterday where he was charged and ordered to attend City of Westminster magistrates' court on June 3.
The allegations followed an investigation by officials at the Independent Police Complaints Commission (IPCC). They are linked to an incident outside the Middle Eastern Yas restaurant in Kensington on July 18.
Dizaei, who was wearing his uniform, arrested a young businessman after a row in which he claimed he was poked with the mouthpiece of a hookah water pipe.
It is the second time Dizaei has been accused of perverting the course of justice and misconduct in public office.
He stood trial at the Old Bailey in 2003 after it was claimed he lied about vandalism to his car. He was cleared on both counts.
Alfred John, chair of the Metropolitan Black Police Association, said the allegations are "outrageous".
He said his friend and colleague was "fully vindicated" in 2003, questioned the motives of his accusers and highlighted the cost to the taxpayer.
Mr John said: "We will call to account those who use the public purse and the law to settle their personal vendettas." Dizaei is being represented by Michael Mansfield QC, who is returning to the criminal courts from retirement.
Mr Mansfield's long list of famous cases include the Bloody Sunday inquiry and the inquests into the deaths of Diana, Princess of Wales, and Jean Charles de Menezes.
The 2003 Old Bailey case was brought in the wake of a massive multi-million-pound secret undercover operation known as Operation Helios.
This failed to find evidence to substantiate claims Dizaei used prostitutes and spied for Iran in 1999 and 2000.
Dizaei was awarded pounds 60,000 in compensation and reinstated to the force where he became a thorn in the side of a series of Scotland Yard commissioners..
