A Metropolitan Police inspector has been arrested on suspicion of racial abuse.
The officer, based in north London, is being investigated by the force's Directorate of Professional Standards (DPS) and the Independent Police Complaints Commission (IPCC) after an incident in Barnet.
The Met said the officer, who was off-duty at the time of the alleged incident at 7.40am on Monday, was arrested and suspended while the incident is investigated.
"He is at present on police bail and has been suspended from duties pending the outcome of the criminal investigation, " a Met spokesperson said.
The IPCC confirmed it's supervising the investigation - the latest allegation of racism by Met officers under investigation by Scotland Yard and the IPCC.
Scotland Yard is facing another case of alleged racism. 28-year-old Edric Kennedy-Macfoy, an off duty black firefighter, claims he was tasered by a group of police officers. He also claims he was arrested without good cause when he went to help the six policemen last year.
There is now "sufficient evidence for a realistic prospect of conviction" of PC Alex MacFarlane, a Crown Prosecution Service review concluded.
Lawyers studied footage appearing to show the officer say to a 21-year-old black man: "The problem with you is you will always be a n*****, yeah?".
Alison Saunders, chief prosecutor for CPS London, said she had advised the Independent Police Complaints Commission to charge PC MacFarlane despite the CPS's decision not to charge him in January.
In March, the complainant's lawyers challenged that decision and, in accordance with standard CPS practice, Grace Ononiwu, Deputy Chief Crown Prosecutor for CPS London, directed that the case be reviewed by a more senior lawyer who was not previously involved.
That review is now complete and the conclusion, based on all the evidence now available, is that there is sufficient evidence for a realistic prospect of conviction to charge Pc MacFarlane with a racially aggravated public order offence contrary to Section 4a of the Public Order Act 1986 and Section 31 of the Crime and Disorder Act 1998.
The Crown Prosecution Service has advised the Independent Police Complaints Commission to charge Scotland Yard PC Alex MacFarlane with a racially aggravated public order offence in relation to the alleged abuse of a suspect during the London riots.
Metropolitan Police Commissioner Bernard Hogan-Howe is due to appear before the Home Affairs Select Committee later.
He is expected to be questioned by MPs about racism in the Met .
The Commissioner, Bernard Hogan-Howe, vowed today the force will become an "implacable enemy" of racists as investigations continue into officers accused of racial abuse.
The Met's policy of 'Stop-and-search' has often left officers open to criti-cism so instead they may now ask suspects for fingerprints before they search them.
But is that any better? Here's Glen Goodman's report.
The Metropolian Police Commissioner has said Scotland Yard must deal better with black suspects.
Speaking on LBC Radio, Bernard Hogan Howe pledged to deal with all allegations of abuse. He also said he wanted at least one in three police officers in London to be from an ethnic minority.
Ten cases of alleged racism are currently being investigated by the police watchdog.
The Metropolitan Police Commissioner, Bernard Hogan-Howe, today vowed to stamp racism out of the force.Read the full story ›
