A Team GB sprinter has accused police of "racial profiling" after she and her partner were stopped and searched in London.
Commonwealth gold medallist Bianca Williams had been with her partner Ricardo in Maida Vale on Saturday when they were stopped.
She told The Times: "It's always the same thing with Ricardo.
"They think he's driving a stolen vehicle, or he's been smoking cannabis."
She added: "It's racial profiling.
"The way they spoke to Ricardo – like he was scum, dirt on their shoe – was shocking. It was awful to watch."
Footage of the incident was posted by former Olympic gold medallist Linford Christie, appearing to show two people – although their faces were not seen – being pulled out of a car in a London street.

The woman sounds frustrated as she tells officers "he didn't do anything" but she grows increasingly distressed about her son remaining in the car.
Christie posted a statement that said: "Was it the car that was suspicious or the black family in it which lead (sic) to such a violent confrontation and finally an accusation of the car smelling of weed but refusing to do a roadside drug test?"
The Metropolitan Police said a car had been stopped in the area on Saturday afternoon after it was seen driving suspiciously.
