An inner London district in Southwark and Lambeth, rooted in the Old College estate and the privately run Dulwich schools.
Matt Arnold, a 46-year-old comedy promoter, was wrongly identified by Sainsbury’s Facewatch facial recognition system at the East Dulwich store and asked to leave, triggering renewed calls to pause or scrap the technology. The incident is being investigated, with Sainsbury’s apologising and pausing the system at the Dulwich branch.
