Mr Dos Santos was speaking at a police misconduct hearing into the incident, footage of which subsequently went viral.

The couple believe they were racially profiled by the Metropolitan Police.

Dashcam footage played at the hearing showed the pair being followed by police while driving to their west London home from training in July 2020.

They were then handcuffed and searched for drugs and weapons by officers after they pulled over outside their property - nothing was found.

Their three-month-old son was in the back seat of their Mercedes throughout the encounter.

Mr Dos Santos, 28, told the hearing he was not trying to "evade" the police and was not driving dangerously.

"I didn't want anything to happen to my family and I wanted to get home," he said.

"I was afraid for the safety of Bianca and my son."

When asked why he should be afraid of the police, Mr Dos Santos said he had "traumatic experiences" as a young black person and had been stopped by the police on "multiple occasions" in the past.

Mr Dos Santos competed for Portugal in the 400m at the Tokyo 2020 Olympics.

Ms Williams, 29, won a gold medal for Team GB in the 4x100m relays at the 2018 European and Commonwealth Games.

The five police officers involved could be sacked if gross misconduct is established.

All five are accused of breaching police standards over equality and diversity.

Four face allegations that their actions amounted to a breach of professional behaviour standards in relation to the use of force.

They are also accused of failing in relation to their levels of authority, respect and courtesy, as well as in their duties and responsibilities.

The officer who was driving the police vehicle is accused of breaching professional standards in the way he carried out his duties and responsibilities or gave orders and instructions.

The five deny the charges.

The hearing continues.
