The Police Data Act sets out specific rules on how long we are permitted to retain police data. The Act specifies time limits for how long police data may be retained. Once this time limit has been reached, the personal data must be permanently deleted. We must, in any case, comply with two different retention periods. Which one we must apply depends on whether a special investigating officer (BOA) carries out day-to-day police duties or is involved in longer-term investigations, such as a social investigator. We explain this below.
The retention period for police data processed for day-to-day policing duties – for example, for issuing fines – is as follows. During the first year after a special investigating officer (BOA) first processes police data, this data is widely accessible to BOAs where necessary for the performance of their duties. In the four years that follow, police data may only be accessed via targeted searches, for example by registration number or name. Finally, police data is retained for a further five years. During this final phase, the data may only be used for purposes such as handling complaints or conducting audits. After this final period, the data is destroyed.
The retention period for police data processed in the context of targeted investigations, for example by social investigators, is as follows. For targeted investigations, police data may be processed for as long as is necessary to achieve the purpose of the investigation. The purpose may, for example, be deemed to have been achieved once a court has finally handed down a judgement. After that, information from an investigation may still be reused for a further six months. An official within the local authority oversees this process. Finally, police data is retained for a further five years. During this final phase, the data may only be used for purposes such as handling complaints or conducting audits. During this phase, the Public Prosecution Service may, for example, still request the information. This only occurs in exceptional cases. Once these five years have elapsed, the data is destroyed.
