Powers of investigators

Investigative authorities

There are number of investigative authorities who have varying powers under which they can carry out raids, conduct searches and seizure of property and require individuals to attend interviews or to provide information or documentation as part of their investigation. These authorities often have memorandums of understanding in place to ensure they can work together when investigating criminal offences (see Practice Note: Memorandum of understanding—criminal investigations and prosecutions).

For a quick guide to the relevant authorities and the scope of their powers, see Practice Note: Dawn raid—table of relevant authorities and the scope of their powers.

Below are some useful links to Practice Notes which provide information and guidance on how to deal with the individual authorities, in particular what to do when they come knocking at dawn, and setting out their relevant investigative powers.
