The comedian was arrested at Heathrow Airport in September 2025 and was subsequently taken to hospital.

The Metropolitan Police have apologised to comedian and campaigner Graham Linehan and acknowledged his "considerable distress" for his arrest over his posts on X in September 2025. Five armed Heathrow airport officers detained the Irish comedy writer on suspicion of inciting hatred under the Public Order Act as he returned from Arizona. The BBC understands a settlement has been reached, which is reported to be £25,000. In a video reacting to the news, Linehan, who now lives in Arizona, said the money will be "very handy" given he has been "fighting against this madness". A spokesperson for the Met said they "recognise the considerable distress caused to Mr Linehan, and have offered our sincere apologies". They had already apologised to Linehan in May, but issued a second apology as well as the settlement. Following the arrest, Linehan was taken to hospital after officials became concerned for his health when they took his blood pressure. His condition was "neither life-threatening nor life-changing" the police said at the time, and he was bailed "pending further investigation".
