A visit to Beasts of London leads me to the mysterious tale of the sighting by four terrified boys of a bear on Hackney Marshes in the 1980s. Don’t remember hearing about this growing up in Hackney – not even the gory detail that two decapitated bear corpses had been found earlier, floating in a nearby river. These bodies are talked about in various forums as the corpse of a giant, or as skinned bears, the result of feuding local circuses. This writer seems to know the real explanation: one of those ‘pointless traditions’ which judging by the number of urban wild beast sightings on the internet is still going strong. Weirdly, it looks like the Hackney bear was immortalised in an episode of Jasper Carrott’s The Detectives.
