The Met has referred itself to the policing watchdog over the controversial stop-and-search of a British sprinter in west London.
Bianca Williams and Ricardo dos Santos, a Portuguese 400m runner, were stopped in Maida Vale on Saturday.
Commonwealth Games gold medallist Williams, 26, accused the Met of racially profiling her partner for driving a black Mercedes.
The Independent Office for Police Conduct (IOPC) will investigate.
Footage of the stop and search has been shared widely on social media.
In a statement the Met said the decision to refer to the IOPC had been taken “due to the complaint being recorded and the significant public interest”.
“Two reviews of the circumstances by the Met’s Directorate of Professional Standards have not identified misconduct for any officer involved,” the force added.
