An accused and his counsel must be notified of an impending lineup, and counsel's presence is a requi-site to conduct of the lineup, absent an intelligent waiver. Otherwise no reference to such identification may be made at trial, and a courtroom identification is not admissible without clear and convincing proof that the testimony is not the fruit of the earlier iden-tification or admission's being harmless. Bank rob-bery witnesses saw Wade in custody before lineup.
