With all this extra camera footage the case for the mysterious stranger seems all the more nonsensical.
The police have reviewed hours and hours of recordings from cameras all around the Coppice and the various exit points, Arden Hall,Accy College, Sandy Lane, Caligen Foam and the Avenue Parade areas to name a few. They also approached car drivers seen in the area for dash cam footage within the relevant time frames. No appeals from them for an unidentified person to come forward has occurred to the best of my knowledge.
That also endorses for me he acted alone and he is not protecting anyone else from his community. Undoubtably though he was coached in his defence position and statements by his parents and maybe his brief before and after giving himself up.
