“(1) A person arrested and held in custody in a police station shall be entitled, if he so requests, to consult a solicitor at any time. .... (4) If a person makes such a request, he must be permitted to consult a solicitor as soon as is practicable except to the extent that delay is permitted by this section. .... (6) Delay in compliance with a request is only permitted: (a) in the case of a person who is in police detention for a serious arrestable offence; and (b) if an officer of at least the rank of superintendent authorises it. .... (8) An officer may only authorise delay where he has reasonable grounds for believing that the exercise of the right .... (a) will lead to interference with or harm to evidence connected with a serious arrestable offence or interference with or physical injury to other persons; or (b) will lead to the alerting of other persons suspected .... but not yet arrested....; or (c) will hinder the recovery of any property obtained as a result of such an offence .... .... (11) There may be no further delay in permitting the exercise of the right .... once the reason for authorising delay ceases to exist.”
