Last december when I was driving along Marylebone Road Westbound to get out of London and was diverted by Police into the Congestion Charge Zone and was caught by TfL camera and consequently I made a representation to explain the case but was told that TfL could not find the record on the traffic diversion occurred. I was asked by the TfL to provide evidence about the traffic diversion. Since I haven't taken any particular note of the police officers involved, I wonder if anyone there has experienced similar case? and if yes, how I should proceed to acquire such an evidence? Any suggestion would be greatly appreciated.
