Extension of detention
136B.—(1) The registered medical practitioner who is responsible for the examination of a person detained under section 135 or 136 may, at any time before the expiry of the period of 24 hours mentioned in section 135(3ZA) or (as the case may be) 136(2A), authorise the detention of the person for a further period not exceeding 12 hours (beginning immediately at the end of the period of 24 hours).
(2) An authorisation under subsection (1) may be given only if the registered medical practitioner considers that the extension is necessary because the condition of the person detained is such that it would not be practicable for the assessment of the person for the purpose of section 135 or (as the case may be) section 136 to be carried out before the end of the period of 24 hours (or, if the assessment began within that period, for it to be completed before the end).
(3) If the person is detained at a police station, and the assessment would be carried out or completed at the station, the registered medical practitioner may give an authorisation under subsection (1) only if an officer of the rank of superintendent or above approves it.
