London’s Metropolitan Police chief warned that officials will not only be cracking down on British citizens for commentary on the riots in the U.K.,but on American citizens as well.

“We will throw the full force of the law at people. And whether you’re in this country committing crimes on the streets or committing crimes from further afield online, we will come after you,” Metropolitan Police Commissioner Sir Mark Rowley told Sky News.

Riots have broken out across the United Kingdom in recent days over false rumors spread online that an asylum seeker was responsible for a mass stabbing at a Taylor Swift-themed dance event that left three girls dead and others wounded. The murders, allegedly committed by a now 18-year-old British citizen born to Rwandan parents, sparked a series of violent protests that tapped into broader concerns about the scale of immigration in the U.K.

Footage of the violent clashes involving anti-immigration protesters and the groups of counter-protesters, some of whom have been seen waving Palestinian flags, has gone viral on social media, and the government is warning that sharing such content may have serious consequences.

One key aspect that makes this apparent crackdown on social media  particularly shocking to critics is that the British government is threatening to extradite American citizens from the U.S. to be jailed in the U.K. for violating their rules about political speech online.

A Sky News reporter asked Commissioner Rowley to further explain his warning, arguing that high profile figures have been “whipping up the hatred,” and that “the likes of Elon Musk” have been getting involved. She then asked what the police force’s plan will be “when it comes to dealing with people who are whipping up this kind of behavior from behind the keyboard who may be in a different country?”

Rowley answered by telling the reporter, “Being a keyboard warrior does not make you safe from the law.”

“You can be guilty of offenses of incitement, of stirring up racial hatred, there are numerous terrorist offenses regarding the publishing of material,” he said. “All of those offenses are in play if people are provoking hatred and violence on the streets, and we will come after those individuals just as we will physically confront on the streets the thugs and the yobs who are taking — who are causing the problems for communities.”

Elon Musk has made headlines for criticizing Prime Minister Sir Keir Starmer’s response to the riots over the past week, suggesting the U.K. is headed toward “civil war.”

He also responded to a video of someone allegedly arrested for offensive online comments with a question, “Is this Britain or the Soviet Union?”

Starmer’s spokesperson said there was “no justification” for Musk’s comments, adding that social media companies “can and should be doing” more to combat misinformation, the BBC reported. He added that such companies “have a responsibility” to stop the spread of criminal activity and limit misinformation.
