Article 39

When a person is arrested on a charge of committing an offence of such a nature and alleged to have been committed under such circumstances that there are reasonable grounds for believing that an examination forthwith of the person will afford evidence as to the commission of an offence, a police officer may arrange for a registered medical practitioner, and for any person acting in good faith in the medical practitioner’s aid and under his direction, to collect or extract blood or other bodily fluid, or to conduct any other non-invasive and non-painful medical procedure, as is reasonably necessary in order to ascertain the facts which may afford such evidence.
