You can be detained in custody for up to a maximum of 48 hours from the time of your arrest.
Once 48 hours has passed from the time of your arrest, you should be released from the Police’s custody on the condition that you promise to a present yourself whenever your attendance is next required (e.g. attending at a Police station to assist with investigations or to attend Court to answer for formal criminal charges).
However, if the Police need to detain you beyond the first 48 hours, they can do so after obtaining the Court’s permission and explaining why your detention should be extended.
