She is alleged to have described one PC as a “black monkey” and a “coconut”.
She is also alleged to have criticised a white constable for being married to a black woman.
She was found guilty of breaching standards of professional behaviour and of discreditable conduct.
The PC, whose identity has not been disclosed, was one of 11 cases of alleged police racism referred to the Independent Police Complaints Commission back in April. The IPCC chose to allow the Met to handle the case internally.
Her dismissal follows complaints from officers based in the London Borough of Wesminster for allegedly using racist language between May 2010 and August 2011.
Acting against racism
Scotland Yard said in a statement: “The MPS is committed to taking action when cases of alleged racism are brought to our attention.
“Any misconduct procedures will take place in accordance with police regulations under the Police Act, in a swift manner whilst ensuring a thorough and diligent investigation.”
Two weeks ago another Metropolitan police officer who was convicted of drunkenly abusing staff at a railway station snack kiosk was dismissed from the force following a gross misconduct hearing.
31-year-old Philip Juhasz told the Pakistani manager of a takeway kiosk in King’s Cross last September to “go back to your f****** country” after he was refused discounted food.
Juhasz was dismissed for breaching standards of professional behaviour – namely authority, respect and courtesy – and for discreditable conduct.
