English translation
The inquiry official shall have the power to issue a summons to the injured person or to any person whose statement there is reasonable ground to believe may be of benefit to the case, to appear at the time and place stated in the summons, and shall then take that person's statement. In taking such a statement, the inquiry official may first have the person giving the statement take an oath or affirmation, and must comply with the provisions of this Code on witnesses. The inquiry official is prohibited from admonishing, discouraging, or using any other trick to prevent a person from giving a statement that the person wishes to give willingly. In cases of offenses relating to sexuality, where the injured person is a woman, the questioning shall be conducted by a female inquiry official, unless the injured person consents otherwise or there is other necessity, and such consent or necessity shall be recorded; and the injured person may request that any person be present during the questioning. Where it is necessary to have the injured person or a witness identify the offender at the arrest stage, or identify the accused in a criminal case, the administrative or police official, or the inquiry official, shall arrange the identification of the offender or the accused at a suitable place and in a manner that can prevent the offender or the accused from seeing the injured person or the witness, having regard to the safety of the injured person or the witness as appropriate to the circumstances, unless the injured person or the witness consents, in which case the consent shall be recorded.

Firm annotation
Placed in Chapter 1 (Ordinary Inquiry), this section governs how the inquiry official secures and takes witness statements. It links to the Code's rules on witnesses and permits an oath or affirmation, while imposing a clear prohibition on admonishing, discouraging, or tricking a person out of testifying willingly. Two protective layers were added over time: female officers must question female sexual-offense victims (subject to consent or necessity), and identification of an offender or accused must be arranged so the suspect cannot see the victim or witness, in the interest of their safety. The identification safeguard here connects with the child-specific procedures in Sections 133/2 and 133/3.
Why this matters in practice
A witness statement can be taken at any suitable place, not only a police station, so long as the summons and questioning rules are followed; a statement that is not genuinely taken from the witness can be attacked as unlawful. If you are called as a witness or an injured person, you are entitled to give your account willingly and free of pressure, and a female victim in a sexual-offense case can insist on a female officer. If you are unsure of your obligations when summoned, read what to know before you go to court in Thailand.

Arrêt de la Cour suprême n° 1172/2566 (2023)
Questioning a person as a witness under Section 133 is distinct from charging; where a person is questioned only as a witness and not summoned to be charged as a juristic person's representative, no charge notification is required.
The Court distinguished witness questioning under Section 133 from the charge procedure. Because a certain person was questioned only as a witness and not summoned to be charged as a representative of a juristic person, the special investigation officers were not required to notify him of any charge.

Arrêt de la Cour suprême n° 2185/2558 (2015)
Section 133 paragraph one empowers the inquiry official to summon the injured person, or anyone whose statement there is reason to believe may be of use to the case, to attend at the time and place stated in the summons. Questioning may therefore be conducted at any place and need not take place at a police station, so the location alone does not make an investigation unlawful. The paragraph imposes no separate requirement that the record be shown to be a statement the witness in fact gave; a challenge on that ground raises a question of evidence for the court to weigh, not a defect in the investigation.
The defendant argued on final appeal that the investigation was unlawful because the inquiry official had not questioned witnesses at the police station, because typed statements had been taken to some witnesses at home for signature, and because some witnesses did not know what the document said or had signed blank paper. The Supreme Court held that section 133 paragraph one allows questioning at any time and place stated in the summons, so questioning away from the police station did not make the investigation unlawful. On the factual challenge it accepted the investigating officer's evidence that he had never had anyone else obtain a witness signature outside his presence, and that he had questioned some witnesses at their homes, and it treated the witnesses' discrepancies as no more than differences of recollection. The investigation was accordingly lawful.

Arrêt de la Cour suprême n° 84/2499 (1956)
Inducing a witness to reverse a truthful statement and shift the blame is contrary to the proper method of investigation under Section 133, which forbids tricks that interfere with willing testimony.
A prosecution witness, after being prompted, changed an earlier account and shifted the acts he had admitted onto the accused. The Court treated this as inconsistent with the lawful method of investigation under Section 133, which bars discouraging or tricking a witness out of a willing statement.

Foire aux questions
La police peut-elle interroger un témoin ailleurs que dans un poste de police ?
Oui. L'article 133, paragraphe 1, autorise l'officier enquêteur à convoquer un témoin à la date, à l'heure et au lieu indiqués dans la convocation ; l'interrogatoire peut donc avoir lieu dans tout lieu approprié, et pas seulement dans un poste de police.
Un agent peut-il faire pression sur un témoin pour qu'il modifie sa déclaration ?
Non. L'article 133 interdit de réprimander, de décourager ou d'utiliser des stratagèmes pour empêcher une personne de faire une déclaration qu'elle souhaite faire volontairement, et un interrogatoire qui manipule un témoin de cette manière n'est pas une enquête légale.
Dans une affaire d'agression sexuelle, une victime de sexe féminin doit-elle obligatoirement être interrogée par une femme ?
En règle générale, oui. L'article 133 exige qu'une enquêtrice soit chargée d'interroger la victime dans les affaires d'agression sexuelle, sauf si celle-ci y consent ou s'il existe une autre nécessité, laquelle doit être consignée par écrit.
