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.

The Met had said officers were patrolling the area in which Ms Williams was stopped because of an increase in youth violence.
But Ms Williams believes she and her partner were targeted because they are black and were driving 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 said on Monday.
"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."
Mayor of London Sadiq Khan told the BBC he was "pleased" that the Met had referred the case as "it's really important that Londoners have trust and confidence in the police and the way the police are policed".
"There are concerns about the how the police behaved so it's right and proper that those concerns are looked into," he said.
Ken Marsh, chairman of the Met Police Federation, said it had been supporting officers involved in the incident and called on the IOPC to "conclude their work in a fair and timely fashion".
He added that "a short clip of an incident widely shared on social media does not always tell the full operational policing story".
BORIS Johnson has refused to apologise for blaming care homes for coronavirus deaths after furious backlash.
Care-home bosses accused the "cowardly" PM of "rewriting history" after he said yesterday facilities had ignored procedures to stop the spread of coronavirus.

Speaking on a visit to Goole in Yorkshire yesterday, the PM insisted the Government was “learning lessons the whole time”.
Pointing the finger of blame at individual care homes, he said: "We discovered too many care homes didn't really follow the procedures in the way that they could have.”
After anger and outrage from care home staff, No 10 refused to apologise.
The PM's spokesman said this lunchtime: "Throughout the pandemic care homes have done a brilliant job under very difficult circumstances.
"The Prime Minister was pointing out that nobody new what the correct procedures were because the extent of asymptomatic transmission was not known at the time."
When asked if Mr Johnson regretted his choice in words, Downing Street repeated the same line saying the PM was only speaking about asymptomatic transmission.
The coronavirus crisis has killed nearly 30,000 elderly Britons.
Mark Adams, chief executive of social care charity Community Integrated Care told Radio 4 he “couldn’t say on national radio” his true feelings about the comments.
He said: “To be honest with you, if this is genuinely his view, I think we're almost entering a Kafkaesque alternative reality, where the Government sets the rules, we follow them, they don't like the results, they then deny setting the rules and blame the people that were trying to do their best.
“You’ve got 1.6 million social care workers who when most of us are locked away in our bunkers waiting out covid and really trying to protect our family, we’ve got these brave people on minimum wage, often with no sickness cover at all, going into work to protect our parents, our grandparents, our children, putting their own health and potentially lives at risk.
“To get perhaps the most senior man in the country turning around and blaming them on what has been an absolute travesty of leadership from the Government I just think it’s appalling.”
It comes as:
The PM vowed not to raise taxes, VAT or National Insurance rates despite massive spending during the coronavirus crisis
Rishi Sunak was set to cut stamp duty for homes up to £500k from tomorrow after fears that delaying it will see the housing market stall for months

Mr Adams demanded the PM take responsibility, and accused him of rewriting history.
He said: “What we are getting is history rewritten in front of us when you could list pages and pages of government failure which the system has had to cope with.
“To get a throwaway comment almost glibly blaming the social care system and not holding your hands up for starting too late, doing the wrong things, making mistake after mistake is frankly unacceptable.”
I think we're almost entering a Kafkaesque alternative reality, where the Government sets the rules, we follow them, they don't like the results, they then deny setting the rules and blame the people that were trying to do their best"
The National Care Forum (NCF), which represents 120 of the UK’s social care charities, hit back by telling the PM to start "turning the dial up on reform and down on blame".
NCF boss Vic Rayner blasted: “Mr Johnson's comments in relation to care homes' following of procedures are neither accurate nor welcome.
"Government guidance has come to the sector in stops and starts - with organisations grappling with over 100 pieces of additional guidance in the same number of days, much of which was not accompanied by an understanding of the operational implications of operating care services.
"Care providers have moved to adopt these new procedures consistently, at pace and with integrity."
The Independent Care Group (ICG) said the vast majority of providers had "done their absolute best in the face of slow and conflicting advice".

Some care home workers were forced to buy their own PPE
ICG chairman Mike Padgham said: "We should not be getting into the blame game and it is wrong to criticise care and nursing homes at this time.
"It is worth remembering that in February the Government agency Public Health England told homes it was 'very unlikely that people receiving care in a care home will become infected' and that homes didn't need to do anything differently.
"It was many weeks later, after most homes had already put themselves into lockdown, that the advice changed."
No10 today refused to apologise for Boris' words.
A spokesman said: “Throughout the pandemic care homes have done a brilliant job under very difficult circumstances.
The PM was pointing out that nobody knew what the correct procedures were because the extent of asymptomatic transmission was not known at the time.”
This morning the business secretary Alok Sharma defended the under-fire PM.
He told BBC Breakfast: "What the PM was pointing out was nobody knew what the correct proceedings were because the extent of the asymptomatic cases was not known at the time.
"Nobody is suggesting that care homes have not done a fantastic job."
Care homes have had to contend with difficult rules while trying to look after vulnerable people - including confining patients to their room if they show signs of the virus.
According to the ONS, one in five people in care homes in England became infected with coronavirus - and more than half of all homes had outbreaks.
Care-home residents over 65 and those with dementia are now able to receive a coronavirus test every 28 days and staff are able to access them every week, the Department of Health announced last week.

Boris Johnson says too many care homes, 'didn't really follow the procedures in the way that they could have'
Downing Street has resisted calls for Boris Johnson to apologise for claiming some care workers "didn't really follow the procedures" during the coronavirus outbreak.
The comments were branded "a real slap in the face" and "clumsy and cowardly" by medics and campaigners - and the prime minister is facing calls to retract them.
Number 10 has stuck by the statement, made in response to a call from the head of NHS England to adequately fund the adult social care sector within a year.
'Too many care homes didn't follow procedures'
"We discovered too many care homes didn't really follow the procedures in the way that they could have," Mr Johnson said on a visit to Goole, Yorkshire, on Monday.
A government spokesperson clarified later that day he had been pointing out "nobody knew what the correct procedures were" because the amount of people with no COVID-19 symptoms transmitting the virus was unknown.

Mr Johnson's spokesman, asked during a Westminster briefing on Tuesday if he would apologise, said: "The PM thinks that throughout the pandemic care homes have done a brilliant job under very difficult circumstances."
Labour's shadow health secretary Jon Ashworth claimed care workers had been left "insulted" and "hurt", called for an apology and challenged the government to explain which care homes didn't follow which procedures.
Sir Keir Starmer said the comments were "shameful".
The Labour leader said: "At least 20,000 people have died from COVID-19 in care homes. Residents went without tests. Staff were left without PPE. And all after a decade of cuts to social care.
"Shameful of Boris Johnson for trying to blame others for his government's failures."

Matt Hancock, the health secretary, declined to publicly criticise the original statement.
"Throughout this crisis, care homes have done amazing work," he told the House of Commons on Tuesday.
"The prime minister was explaining, because asymptomatic-type transmission was not known, the correct procedures were therefore not known.
"We've been constantly learning about this virus from the start and improving procedures all the way through."
And the business secretary stuck to the same script when he spoke to Sky News' Kay Burley@Breakfast earlier on.
Alok Sharma said he "noted" the criticism of Mr Johnson but insisted "nobody knew what the correct procedures were at the time".
But voices from outside government have been highly critical.
Special report: The killer in our care homes
Nadra Ahmed, the chair of the National Care Association, told Sky News: "I'm absolutely stunned the prime minister thought it was appropriate for him to make that comment and I think he should retract that comment and apologise."
Vic Rayner, executive director of the National Care Forum, said: "Care homes across the country were dealing with an extraordinary amount of different guidance that was coming out from government on an almost daily basis.
"So for the suggestion that they were not following procedures as laid out is totally inappropriate and, frankly, hugely insulting."
The Independent Care Group's chairman Mike Padgham said it was "upsetting" to hear Mr Johnson's comments and described them as "a real slap in the face for those workers after they have given and sacrificed so much".
"I think this - at best - was clumsy and cowardly," he continued.
"But, to be honest with you, if this is genuinely his view, I think we're almost entering a Kafkaesque alternative reality where the government set the rules; we follow them; they don't like the results; and they then deny setting the rules and blame the people that were trying to do their best.
