Met police officer suspended in racist abuse inquiry
After previously deciding not to press charges, the CPS is reassessing the alleged events of 11 August last year.
Neither of the other two police officers are currently suspended.
'Personally considered matter' One has been placed on restricted duties on an unrelated matter while the other remains on full duties.
The CPS confirmed earlier that having decided not to press charges, it would be assessing the case again.
Grace Ononiwu, deputy chief crown prosecutor for the CPS London, said: "Lawyers for the complainant have written to the CPS and asked us to review our decision.
"I have considered the matter personally and directed that all of the evidence should be reconsidered and a fresh decision taken by a senior lawyer with no previous involvement in this matter.
"That process will be completed as soon as possible," she added.
A Scotland Yard spokesman confirmed that a complaint had been received.
He said: "These are serious allegations; any use of racist language or excessive use of force is not acceptable.
Misconduct investigation "The MPS's Directorate of Professional Standards referred this case to the IPCC who are independently investigating.
"Following the alleged incident, three officers were the subject of a misconduct investigation.
"One of the officers has been suspended in relation to this matter pending the result of the IPCC investigation.
"One of the officers has been placed on restricted duties on an unrelated matter and another remains on full duties.
