(1)Where a police officer of the rank of superintendent or above who is responsible for the police station at which a person is detained has reasonable grounds for believing that—
(a)the detention of that person without charge is necessary to secure or preserve evidence relating to an offence for which he is under arrest or to obtain such evidence by questioning him;

(2)Where an officer such as is mentioned in subsection (1) above has authorised the keeping of a person in police detention for a period expiring less than 36 hours after the relevant time, such an officer may authorise the keeping of that person in police detention for a further period expiring not more than 36 hours after that time if the conditions specified in subsection (1) above are still satisfied when he gives the authorisation.
(3)If it is proposed to transfer a person in police detention to another police area, the officer determining whether or not to authorise keeping him in detention under subsection (1) above shall have regard to the distance and the time the journey would take.
(4)No authorisation under subsection (1) above shall be given in respect of any person—
(a)more than 24 hours after the relevant time; or

an opportunity to make representations to him about the detention.
(7)Subject to subsection (8) below, the person in detention or his solicitor may make representations under subsection (6) above either orally or in writing.
(8)The officer to whom it falls to determine whether to give the authorisation may refuse to hear oral representations from the person in detention if he considers that he is unfit to make such representations by reason of his condition or behaviour.
(9)Where—
(a)an officer authorises the keeping of a person in detention under subsection (1) above; and

[F9(12)Subsection (13) applies where—
(a)a person is released under subsection (10), and
(b)a custody officer determines that—
(i)there is not sufficient evidence to charge the person with an offence, or
