In a new turn in the Sohrabuddin Sheikh fake encounter case, senior Gujarat-cadre IPS officer Geetha Johri has accused the CBI of pressurising her to implicate some political leaders, including arrested BJP leader Amit Shah.

In a curative petition filed with the apex court, she has sought the removal of Balwinder Singh, CBI's Special Director who is supervising the investigation into the case, and said he be made a witness in it.

Johri accused CBI of pressurising her to implicate some politicians, including Gujarat's former minister of state for Home Amit Shah who has already been arrested in connection with the killing of Sheikh in a fake encounter with police in Ahmedabad in 2005.

She alleged she had been asked by CBI to depose in a particular manner in the case and that her personal assistant was threatened by CBI.

Seeking Balwinder Singh's removal as supervisor of the probe into the case, Johri said in the petition that she herself had interrogated him in connection with the case when he was the Police Commissioner of Hyderabad in 2007.

She said Singh should be made a witness in the case.

The curative petition also challenged the apex court's decision not to expunge adverse remarks made against her in connection with the case.

The curative petition was filed after the Supreme Court had dismissed her petition seeking a review of the judgement in which adverse remarks were made against Johri while handing over the probe into the case to CBI from Gujarat police.
