A Team GB sprinter is considering suing the Metropolitan Police after accusing officers of racially profiling her and her partner in a stop and search.
Bianca Williams and Ricardo dos Santos, a Portuguese 400m runner, were stopped in Maida Vale on Saturday.
Ms Williams, whose three-month-old son was in the car during the incident, called it an “awful experience”.
The Met said officers were patrolling the area because of an increase in youth violence.
But the European and Commonwealth Games gold medallist believes the couple were targeted because they are black and drive a Mercedes.
“They [the officers] said there’s a lot of youth violence and stabbings in the area and that the car looked very suspicious,” she told BBC Radio 4’s Today programme.
“They see a black male driving a nice car, an all-black car, and they assume that he was involved in some sort of gang, drug, violence problem.”
Footage of the stop was shared widely on Twitter after being posted by former Olympic medallist Linford Christie, who questioned why the vehicle had been targeted.
The Met said a 25-year-old man and a 26-year-old woman were searched when a car was stopped in Lanhill Road and nothing was found in the vehicle or in the possession of the man and the woman, according to the force.
In a statement on Sunday evening the Met said the Mercedes was stopped after it was seen driving suspiciously, including on the wrong side of the road, and that the driver had sped off when asked to stop.
But this was rejected by Ms Williams, who said: “That is false, we were never on the wrong side of the road. We were driving down through single-width roads.
“We only found out about us driving on the wrong side of the road once they tweeted.
“This isn’t the first or fourth or fifth time, it must be about the tenth. It’s getting ridiculous.
“We are planning on taking it down the legal route. I feel very hurt by their actions, and to witness my partner being taken away and for me to be taken away from my son, my heart hurts.”
The Met said officers from the Directorate of Professional Standards have reviewed footage from social media and officers’ bodycams and were satisfied there was no concern around the officers’ conduct.
London mayor Sadiq Khan said he takes allegations of racial profiling “extremely seriously” and he has raised the case with the Met.
The Independent Office for Police Complaints said it has not yet received an official complaint.
