Police have confirmed that they have CCTV of the person(s) involve and also (thanks to this site) we have a name and address of a suspect - hopefully only a matter of time. If the person who stole it is reading this then simply return the bike to Cabot Circus security - today would probably be in your best interests (KM?)
