"Preliminary inquiry suggested the unidentified caller could (be) a lawyer," police sources said while refusing to divulge details.
Shaikh and two other witnesses identified Salman Khan saying they had seen him getting down from the car which had met with an accident in suburban Bandra on September 28, 2002.
The witnesses were among the injured who were run over by the car when they were sleeping on a footpath near American Express Bakery on that day.
The court is conducting the re-trial of this case after the charges of culpable homicide were added recently. One person was killed and four persons injured in the incident after which police booked Salman on the charge of rash and negligent driving, besides other charges. Recently, an additional charge of culpable homicide not amounting to murder was slapped against the actor. The charge attracts jail term of ten years.
