Arrest of French publisher in London referred to police watchdog

Report says detention of Ernest Moret was wrong after he was held for almost 24 hours by counter-terrorist police

The arrest in London of a radical French publisher under counter-terrorist powers has been referred to the police watchdog after the reviewer of terrorism legislation found that it was wrong.

Ernest Moret, 28, was held for almost 24 hours by counter-terrorist police and asked about his opinion of Emmanuel Macron and participation in anti-Macron protests after he arrived at St Pancras station in April for a book fair.
