Australian Formula One driver Jack Doohan has appealed for online abuse of his family to stop after they were targeted on social media following his replacement by Alpine earlier this month.

Doohan, 22, the son of former motorcycling world champion Mick Doohan, was dropped by the Alpine team after just six races. He was replaced by Argentina’s Franco Colapinto, who finished 16th at Sunday’s Emilia Romagna Grand Prix in Italy after a crash during qualifying.

Writing to his nearly 500,000 followers on Instagram, Doohan said a fake post falsely attributed to his father had been circulated online to damage his reputation.

"Please stop harassing my family. I didn't think I would have to get to this point," Doohan wrote, alongside a screenshot of the fake image.

The fabricated post featured a photo of Colapinto after his crash, alongside a comment supposedly from Doohan’s father reading, "Very impressive."

"Multiple Argentine outlets falsely reported the fabricated image, which triggered the online abuse of my family," Doohan added. The young driver currently serves as a reserve for Alpine.

Alpine also issued a statement condemning the harassment.

"We encourage everyone to remember that behind the visor of these superhuman athletes there is a person, an individual with feelings, family, friends and loved ones," the team said.

"As a team we cannot condone online abuse and urge all fans of this sport we love to be kind and respectful."

Formula One heads to Monaco this weekend for the next race on the calendar.
