I have been informed by the PSNI that its call grading policy (which is currently under review) grades calls into four categories as follows:
emergency response;normal response;scheduled response; and no attendance
PSNI's policy in respect of a call in which no attendance is appropriate is defined as:
an attendance of an officer is not required and the incident can be concluded by the person taking the call or the incident should be dealt with by an outside agency.
Further guidance on such calls states that they are to be resolved by telephone, using a problem-solving approach appropriate to the callers needs. Where the scenario of a call relates to a minor crime report where no investigation is possible, no attendance is required.
The PSNI will therefore attend all crime scenes except where it relates to a minor crime report where no investigation is possible.
