Commentary on Sections Part 9 – Power of Police to Remove Person to Place of Safety Section 149 - Record of detention to be kept
This section requires the “appropriate officer” (as defined in section 160) to make a written record of a person’s detention. The record must be made as soon as practicable after the decision to detain the person has been taken, and must be made in the presence of the detained person. If the person is incapable of understanding what is being said, is acting in a violent manner or is in urgent need of medical attention, then they do not have to be present when the written record is made.
