From Pc West's cross-examination: "Q So the first thing you do is ring H.Q. Information Room. A. That is correct, yes."
Pc West went on to say that he was told that Witham Police Station covered Tolleshunt D'Arcy and he contacted them, then: "Q Did you tell them what you had been told? A. Yes, I spoke to an officer on the personal radio link between ourselves and Witham Police Station relayed the message that I had received from Mr. Bamber in order that they could respond to it."
It would seem that the above is what led the Appeal Court to state (incorrectly) "Using a radio link PC West contacted Malcolm Bonnet at the Chelmsford H/Q Information Room." So much for the Appeal Court's attention to detail.
Pc West implies that Witham Police Station arranged a response to JB's call. To whom did they relay the information and who at Witham did this? Bear in mind that car CA05 clearly travelled from a considerable distance away (as its arrival at WHF was logged by Bonnett as occurring at 04:23), and seems to have been based at Chelmsford. On the other hand, car CA07 (based at Witham), according to Mr Bonnett, was contacted directly by him, and sent by him to WHF. Mr Bonnett's 2001 statement doesn't mention referring Pc West to Witham.
