Saka’s comments added to growing calls for the platforms to take action against hate speech.
On Wednesday, Mr. Johnson said he had warned representatives from Facebook, Instagram, Twitter, TikTok and Snapchat that they would face fines under Britain’s planned online safety legislation if they failed to remove hate speech and racism from their platforms.
England’s Football Association also released a statement, saying that “social media companies need to step up and take accountability and action to ban abusers from their platforms, gather evidence that can lead to prosecution and support making the platforms free from this type of abhorrent abuse.”
Facebook, which owns Instagram, said it was removing comments and accounts that had directed abuse at England’s team and was providing information to law enforcement authorities. Four people have been arrested over online racist attacks aimed at England’s players, the British police said on Thursday.
Twitter said it had removed more than 1,000 tweets and permanently suspended “a number of accounts” for violating its rules.
