Before these contentions could be appreciated, it was put to counsel for the petitioner that petitioner had made an extra judicial confession to one Tej Vir Singh and in the testimony of Tej Vir Singh name of the petitioner had surfaced. In the present case, truck was left at the spot. Therefore, it can be safely said that police was carrying on the investigation to find the driver of the truck and the petitioner had come forward and made extra judicial confession before Tej Vir Singh who had produced the petitioner before the police. Therefore, after extra judicial confession was made, name and particulars of the petitioner were known. In this context identity of the petitioner in Court assume importance. It has been held by the Courts that identification in Court is a substantive piece of evidence and test identification is to be used for corroboration. The trial Court held that there is no enmity between accused-petitioner and Tej Vir Singh. No argument was raised before the Courts below to impeach the credibility of the eye witnesses. Extra judicial confession alone is not only sufficient, but can also be used to corroborate identity of accused established in the Court.
