Throughout the Austria F1 race weekend, a number of fans have posted on social media about harassment they have experienced, including the use of homophobic and racist slurs, catcalling and other abusive comments.
The fan reports were passed on to F1, which responded with a statement that it would be taking further action.
“We have been made aware of reports that some fans have been subject to completely unacceptable comments by others at the event,” F1 said in a statement.
“We have raised this with the promoter and security and will be speaking to those who have reported these incidents and are taking this very seriously.
“This kind of behaviour is unacceptable and will not be tolerated and all fans should be treated with respect.”
Fan behaviour has already been in the spotlight this weekend in Austria after Lewis Hamilton’s crash during qualifying on Friday was met with cheers and celebrations from some Max Verstappen fans in the grandstands.
More than 50,000 Dutch fans are understood to have travelled to Austria for this weekend’s race, which will have a sell-out crowd of 105,000 on Sunday.
Hamilton said that he found it “mind-blowing” fans would cheer a crash, particularly without knowing the condition of the driver.
“I'm grateful that I wasn't in hospital, and I wasn't heavily injured, but you should never cheer someone's downfall or someone's injury or crash,” Hamilton said.
“It shouldn't have happened in Silverstone, even though it wasn't obviously a crash, and it shouldn't have happened here.”
Verstappen was booed by fans during his interview after qualifying at Silverstone last weekend, as well as being cheered when he spun during the session.
“The booing is a personal attack on the driver,” said Mercedes F1 boss Toto Wolff. “Fans should just put themselves in the position and that they are standing up there and they are being booed and I think that's not right for the driver, that Christian [Horner] was being booed in Silverstone.
“I don't think that's right. So hopefully we can talk sense. We love the fans, we want them to be there, we want them to be emotional and passionate, but maybe when it gets personal that shouldn't happen."
