[6] Williams lives in Maida Vale and in addition to her track career, works as a part-time tennis coach.

[9] On 4 July 2020, Williams and dos Santos accused the Metropolitan Police of racial profiling after having their car stopped and searched whilst returning from a training session.

[10] Williams subsequently spoke with The Times and accused the police of racial profiling and acting violently towards her family.

[9][11][12] The Met released a statement, saying the vehicle Williams was travelling in had been on the wrong side of the road, and that the driver had sped off when asked to stop.

[21] On 4 October 2024, the Police Appeals Tribunal overturned the gross misconduct outcome and reinstated the jobs of the two officers as well as ordering they receive back pay.

Williams pleaded guilty to failing on three separate occasions to advise the police, in writing, who it was that had been driving her Tesla Model 3 car.

The athlete told the court that she wasn't the driver at the time of the alleged incident and that imposing a ban may jeopardise her chances of qualifying for the 2024 Olympic Games.
