Two Metropolitan Police officers who carried out a stop-and-search of two athletes in west London committed gross misconduct, a tribunal panel has found.
British world championships medallist Bianca Williams, 29, and Portugal Olympic sprinter Ricardo Dos Santos, 28, say they were racially profiled.
They were handcuffed and searched outside their Maida Vale home while their baby was in the car in July 2020.
Ms Williams filmed it and their coach Linford Christie posted it online.
During the incident, the couple were pulled over by officers as they returned from a training session and searched on suspicion of having drugs and weapons, but nothing was found.
Five Met officers were accused of gross misconduct, which they denied.
A disciplinary hearing found PC Jonathan Clapham and PC Sam Franks lied about smelling cannabis in Mr Dos Santos' car and so had breached professional standards of police behaviour in relation to honesty and integrity.
The panel said it was likely the smell had emanated from another area.
The hearing was told those officers were "not seen to attempt to verify the smell", which led to them becoming "trapped in a lie" when they gave evidence.
Panel chairwoman Chiew Yin Jones said their behaviour amounted to gross misconduct.
The two officers face being sacked from the force. Sanctions against them are set to be delivered by the panel on Friday.
Acting Sgt Rachel Simpson, PC Allan Casey and PC Michael Bond were found by the panel not to have committed gross misconduct and all allegations against them were not proven.
'Driving while black'
Ms Williams and Mr Dos Santos complained to the police watchdog about what had happened to them, saying they had been racially profiled because Mr Dos Santos was "DWB, driving while black" in a Mercedes. The watchdog brought a case against the officers.
Karon Monaghan KC, for the Independent Office for Police Conduct (IOPC), told the disciplinary panel at the start of the hearing that the watchdog's case would say there was "institutional discrimination" in the Met Police.
Mr Dos Santos told the panel while giving evidence that he had been "afraid" for the safety of his partner and his three-month-old son.
Mr Dos Santos was stopped nine times within four weeks of buying a car in 2018, the panel heard.
Earlier this year, Ms Williams won bronze in the 4x100m at the World Athletics Championships in Budapest.
She also won gold in the same discipline at the European Championships in 2018 and silver in 2016.
At the Commonwealth Games in 2022 and 2018, she won 4x100m gold twice representing England.
She and Mr Dos Santos, who competed in the 400m at the Tokyo 2021 Olympics, are both coached by Mr Christie, the British former 100m Olympic champion.
Footage of part of the stop-and-search filmed by Ms Williams was shared widely on social media, after being posted by Mr Christie.
