<p>The length of time a suspect is held in police custody before being released is unrelated to the police's power (and duty) to sieze potential evidence for further examination or to require e.g. the surrender of a passport as a condition of pre-charge bail (along with the requirement not to apply for international travel documents or tickets etc).</p>
