Article 53

The police may interview any witness who has information relevant to an offence.

The police may issue a directive to a witness to appear at the police station for questioning about the offence. It shall be the duty of any person to cooperate with this directive, provided, however, that if the person is a suspect, the provisions of Article 54 shall apply and provided further that it shall not be a crime for a person to fail to comply with a directive issued pursuant to this Article.

The witness shall answer truthfully all questions put to him, but he may refuse to answer any question the answer to which would have a tendency to expose him to a criminal charge.

Any statement made shall be reduced to writing and signed, or recorded otherwise and shall be made part of the record of the police investigation in the case.

No police officer or other person in authority shall offer, use, or cause to be offered or used any force, inducement, threat, promise or any other improper method to any person examined by the police.

No police officer or other person in authority shall prevent or discourage by whatever means any person from making, or from requiring to be recorded, in any manner, in the course of the police investigation, any statement relating to such investigation, which statement the person may be disposed to make of his own free will.
