New Delhi, Nov 22 (IANS): After a CBI officer testified in a court that Amit Shah was among the "principal conspirators" in the 2006 Tulsiram Prajapati fake encounter case, Congress President Rahul Gandhi on Thursday took a swipe at the BJP saying it was "appropriate" for the BJP to have such a man as its President.

"The Gita says you can never escape the truth and so it has always been. Sandeep Tamgadge has called Amit Shah a "key conspirator" in his testimony. It's completely appropriate for the BJP to have such a man as its President," tweeted Gandhi.

The Congress leader's remarks came a day after Tamgadge, the chief investigating officer in the Prajapati case, told a CBI court that Shah and former IPS officer D.G. Vanzara were the "principal conspirators".

Tamgadge in his deposition, also said that Shah was part of "criminal-politician-police nexus" and Prajapati, Sohrabuddin Shaikh and Sohrabuddin's wife Kausar Bi were killed as a result of this nexus.

A Nagaland cadre IPS officer, Tamgadge investigated both the cases involving the killings of Sohrabuddin and Prajapati allegedly in staged encounters.

The CBI had earlier indicted and arrested Shah of being a "part of the larger conspiracy to kill Sohrabuddin, subsequently his wife and finally Prajapati. But he was later discharged of the charges by a CBI court in December 2014 months after the Narendra Modi-led BJP came to power at the Centre.
