Overview

• The Metropolitan Police confirm a man in his 50s was detained at 1 p.m. on Sept. 1 after arriving from Arizona and arrested in relation to posts on X.
• Linehan says the case concerns three April posts, including a line suggesting to "punch" a trans-identified male in a female-only space, which he describes as a joke.
• After being taken into custody, officers raised health concerns and he was taken to hospital; the force says his condition was neither life-threatening nor life-changing.
• Bail includes a prohibition on using X, with a further police interview expected in October as inquiries continue.
• The arrest has drawn swift reactions from politicians and campaigners, and comes days before a separate Westminster court appearance on harassment and criminal damage charges he denies.
