Mr. Andrew O'Sullivan:

There is no real change to the original procedure. Approximately 15% of incidents are closed without further action. One could call that cancellation in some sense. That might mean, for example, an incident is reported multiple times. If there is a major incident or a traffic incident on the M50, that will be recorded multiple times. It could be the caller calls back and we satisfy ourselves that it does not require further action. Typically, that will be in the case of alarm calls. The vast majority of incidents that are closed without further action relate to traffic incidents where there are multiple calls or alarms that were set off by accident.
