Overview

• London’s Metropolitan Police said a man in his 50s was arrested at Heathrow on suspicion of inciting violence in relation to posts on X and later bailed pending further investigation.
• Graham Linehan, 57, identified himself as the detainee and said five armed officers met him after his American Airlines flight from Arizona and informed him of the arrest over three tweets.
• After being taken into custody, officers raised health concerns and he was moved to a hospital; police said his condition was neither life‑threatening nor life‑changing.
• Linehan says his sole bail condition prohibits posting on X until a further interview expected in October, and the Met said airport officers’ firearms were not drawn during the arrest.
• The arrest drew sharp reactions from public figures and politicians, while Linehan is also due in Westminster Magistrates’ Court this week on separate harassment and criminal damage allegations that he denies.
