In 2018, a crudely made bomb was found in a car park in central Edinburgh. Later, blog posts by an unknown author appeared on a Mexican eco-anarchist website, in both Spanish and English, claiming responsibility for said bomb.

Our own Professor Tim Grant was contacted by Police Scotland to build a profile of the author. Two years later, the police contacted Tim again after identifying a potential suspect.

Dr Isobelle Clarke (Lancaster University) joined Tim in using comparative authorship analysis to determine who may have been responsible for these posts.
