On 1 November, 27-year-old Paul Gardner, a former student at Cambridge and now a consultant, was showing two large posters of late-term unborn babies in and out of the womb, along with the image of an aborted foetus.

A member of the public complained to officers that the images were “offensive,” and Mr Gardner was arrested under Section 4A of the Public Order Act. He was taken to Cambridge police station and held for about six hours before being released; police later confirmed that no offence had been committed.
