In any cases where identification may be an issue, a record must be made of the description of the suspect first given by a witness. This should be disclosed to the suspect or his solicitor. If the ability of a witness to make a positive visual identification is likely to be an issue, one of the formal identification procedures in Pace Code D, para 3.5–3.10 should be used, unless it would serve no useful purpose (e.g. because the suspect was known to the witnesses or if there was no reasonable possibility that a witness could make an identification at all).
