Overview

• Miles Pickering was detained at the 9 August Parliament Square protest after an officer misread his T‑shirt as support for the proscribed group and was de‑arrested when police saw it read 'Plasticine Action'.
• The Metropolitan Police said a scarf had partially obscured the wording and that he was arrested on suspicion of a Terrorism Act offence before being released at a nearby processing point.
• The shirt carries an anti‑AI message with the character Morph and does not reference Palestine Action.
• Pickering is selling the design to raise money for Medical Aid for Palestinians, reporting international sales.
• Scotland Yard says it has made more than 700 arrests since the 5 July ban, including 532 at the 9 August demonstration; Police Scotland said no arrests at a Glasgow rally where the same shirt was seen.
