The public prosecutor in the 2002 hit-and-run case of Bollywood actor Salman Khan said the doctor who had collected the blood samples of the actor has requested the sessions court for police protection."Dr. Shashikant Pawar has asked for a constable till the next hearing. The court has asked him to give a written application but he said he will not give a written application but just prayed for security," Public Prosescutor Pradeep Gharat said.Meanwhile, Senior Advocate Abha Singh said a witness asking for police protection was a serious matter. "Inquiry should be done and if the truth is found, then Salman Khan's bail should be rejected," she said. "CrPC [Code of Criminal Procedure] clearly says that if any witness is influenced, then in that case, the bail can be cancelled," Singh added.
