British far-right activist Tommy Robinson detained at Heathrow under anti-terror laws

British far-right activist Tommy Robinson was detained at Heathrow Airport on Sunday after returning from Russia, where police questioned him under anti-terrorism laws and seized his electronic devices, according to multiple reports published on Monday.

The activist, whose real name is Stephen Yaxley-Lennon, was stopped upon arrival at London’s Heathrow Airport on 14 June 2026 and held for questioning by officers from the Metropolitan Police’s Counter Terrorism Command . Authorities confirmed they had taken possession of some of his equipment during the search, though neither the Metropolitan Police nor Robinson’s representatives have provided further details about the nature of the material seized.

The detention follows a video posted by Robinson several days earlier showing a knife attack in Belfast, Northern Ireland, which he claimed was carried out by a Sudanese man. The footage sparked violent protests in the city, prompting local authorities to deploy additional security measures . Police in Northern Ireland have since linked Robinson’s online activity to the unrest, with investigators examining his role in inciting the disturbances.

Robinson, a prominent figure in the UK’s far-right movement, has long been associated with anti-immigration and anti-Islam campaigns. His arrest at Heathrow marks the latest in a series of legal confrontations with authorities, including previous convictions for contempt of court and public order offences. Slovakian news outlet Aktuality.sk reported that British authorities had briefly held Robinson and confiscated his phone while investigating his involvement in the Belfast riots .

The Metropolitan Police have not issued an official statement regarding the grounds for Robinson’s detention under terrorism legislation, though the use of such powers suggests authorities are probing potential links between his activities and broader security threats. Robinson’s supporters have condemned the arrest as politically motivated, while critics argue it reflects growing concerns over the influence of far-right figures in stoking communal violence.

As of Monday, Robinson remains in the UK pending further investigation. The case has reignited debates over the balance between free speech and public order, with civil liberties groups calling for transparency over the legal basis for his detention. Further updates are expected as police complete their review of the seized material.
