British anti-Islam activist Tommy Robinson said he was detained at Heathrow Airport on Saturday and had his phone seized, after a week when he posted heavily online about racist and anti-immigrant riots in Northern Ireland.

Robinson, whose real name is Stephen Yaxley-Lennon, said on X he was held on Saturday evening for around three hours under the Counter-Terrorism and Border Security Act.

“My phone has been seized by the police,” he said on X. “Please help kick off my legal fund for defence.”

Robinson tweeted repeatedly last week about violence that swept Belfast after a video went viral showing the brutal stabbing of a man, who lost an eye in the attack. A Sudanese man has been charged with attempted murder. Police have said they are not treating the attack as terrorism.
