at any time before the expiry of the said 6 hours.

(7)If—
(a)an application for a warrant of further detention is made after the expiry of 36 hours after the relevant time; and

(12)The period shall not be longer than 36 hours.
(13)If it is proposed to transfer a person in police detention to a police area other than that in which he is detained when the application for a warrant of further detention is made, the court hearing the application shall have regard to the distance and the time the journey would take.
(14)Any information submitted in support of an application under this section shall state—
(a)the nature of the offence for which the person to whom the application relates has been arrested ;
(b)the general nature of the evidence on which that person was arrested;
