Six-time Formula 1 champion Lewis Hamilton is set to be investigated by the FIA after wearing a T-shirt in honour of medical technician Breonna Taylor at Sunday's Tuscan Grand Prix, according to the Daily Mail.
Taylor was shot dead at her home in Kentucky on March 13 during a drugs search carried out by police.
The incident, which sparked protests across the US, is still being investigated by the Kentucky Attorney General.
Hamilton donned the T-shirt which read, 'Arrest the cops who killed Breonna Taylor' prior to the Grand Prix at the 'taking a knee' ceremony, and then again on the podium as he celebrated another race win to extend his lead at the top of the Drivers' Championship.
However, with Taylor's case still ongoing, senior F1 figures are believed to be concerned that Hamilton's actions were potentially 'political'. FIA rules forbid political statements, meaning that the Brit could be reprimanded by the governing body.
On the track, the 35-year old picked up the 90th win of his career, moving him to within one victory of Michael Schumacher's all-time record.
It was far from a straightforward afternoon for the Brit, though, with eight cars failing to finish, and the race having to be restarted twice after serious crashes.
Speaking after the race, Hamilton reflected on the struggles that he had to overcome during the chaotic Grand Prix, whilst also paying tribute to Taylor.
"It was like three races in one day. Just incredibly tough. We had a difficult start.
"The heat and keeping Valtteri (Bottas) behind, who has been quick all weekend, was not easy. I was behind at the beginning. Total focus was needed for the restarts. It was really, really hard.
"Keeping that over one-second gap was crucial as I didn't want them [race rivals] to have DRS on that 1000m straight. Justice for Breonna Taylor," he said.
Hamilton now holds a 55-point lead over teammate Valtteri Bottas in the standings, with eight races remaining.
