Fake encounter: No evidence against Modi, CBI says NEW DELHI: A day after law minister Kapil Sibal claimed that Narendra Modi was a "potential accused" in Tulsi Prajapati fake encounter case and slammed CBI for not questioning him, the agency discarded his allegations, calling it "political statements". A senior CBI officer said thorough investigations didn't yield any prosecutable evidence against the Gujarat CM. The officer said they had questioned all those related to the case, examined call details and circumstances before filing the chargesheet in 2012. "We have already examined all the material cited by Kapil Sibal before filing the chargesheet. We were satisfied that there was no prosecutable evidence on record to link Modi with the encounter," said the officer. CBI refused to give an official reaction to Sibal's allegations and call details shared by him with the media. An officer said they had already charged close Modi aide Amit Shah and Gujarat police officers in the case. "We don't have any investigation pending in the case," he said. He said the agency had examined accused police officer DG Vanzara's letter, written from inside the jail accusing the Gujarat government of ignoring the police officers, but it did not find any evidence against anybody in CM's office. "CBI officers know their work - who to be questioned according to available evidence," said the officer. Sibal, while giving purported call details of conversations between police officer Rajkumar Pandian and Parag Shah who he said worked in the CM's office, had said: "Modi is a potential accused. The circumstantial evidence is clear. We are wondering why the CBI has not arrested Parag Shah and why Modi has not been interrogated." CBI had charged Amit Shah in Prajapati fake encounter case alongwith 19 others. Prajapati was killed near Chhapri village near Danta in Palanpur on December 28, 2006 in an allegedly fake encounter. In its chargesheet, CBI had said that Prajapati was a witness in the Sohrabuddin case and his killing was part of a larger conspiracy in which Shah, then junior home minister, was involved. Sohrabuddin and his wife Kauser Bi were allegedly abducted by the Gujarat's Anti-Terrorist Squad (ATS) from Hyderabad and killed in a fake encounter near Gandhinagar in November 2005. Prajapati, said to be a Sohrabuddin's accomplice, was also subsequently eliminated by ATS, CBI had said.
