Written grounds of arrest are mandatory; oral explanation alone can vitiate detention and support bail despite prima facie allegations.

Failure to communicate the grounds of arrest in writing, and in a language understood by the accused, vitiates the arrest and detention; verbal explanation alone is insufficient and later service of remand papers does not cure the defect. Although the record showed prima facie material linking the accused to alleged smuggling activity, including Section 108 Customs Act statements and the air-ticket transaction, the arrest memo disclosed only oral communication of grounds. On that basis, the Karnataka HC held the arrest procedure non-compliant with mandatory constitutional and statutory requirements and granted bail with conditions.

Issues: Whether the petitioner was entitled to bail under Section 439 of the Code of Criminal Procedure, 1973 in view of the alleged non-compliance with the requirement of communicating the grounds of arrest in writing.

Analysis: The materials on record indicated a prima facie case connecting the petitioner with the alleged smuggling activity, including the statements recorded under Section 108 of the Customs Act, 1962 and the transaction relating to the air tickets. However, the arrest memo itself showed that the petitioner was only verbally explained the grounds of arrest. The governing legal position requires the grounds of arrest or detention to be communicated in writing and in a language understood by the accused. Non-compliance with that mandate vitiates the arrest and detention, and the defect is not cured merely because the remand papers were later served.

Conclusion: The petitioner was held entitled to bail because the arrest and detention were prima facie vitiated by failure to communicate the grounds of arrest in writing.

Final Conclusion: Bail was granted with conditions, notwithstanding the existence of prima facie incriminating material, on the ground that the arrest procedure did not satisfy the mandatory constitutional and statutory requirements.

Ratio Decidendi: Where the law requires communication of the grounds of arrest in writing, verbal explanation alone is insufficient and non-compliance renders the arrest and detention illegal, justifying bail despite prima facie allegations.
