CGST arrest commences when the person is actually deprived of liberty and placed in custody, not merely when present during a search, inquiry or statement recording. The twenty-four-hour period for production before a Magistrate runs from that actual arrest. Where a judicial undertaking requires seven working days' prior notice of arrest, a summons requiring attendance, evidence or documents is insufficient because it does not communicate a contemplated arrest. The Commissioner's arrest authorisation must contain and disclose reasons to believe, supporting material and application of mind before arrest. An arrest memo cannot substitute for that authorisation; failure of prior communication vitiates the arrest and later remand cannot cure the defect.
