Ahmedabad: Suspended IPS officer Sanjeev Bhatt was questioned by the CBI, probing the 2005 Sohrabuddin Sheikh fake encounter case, in connection with the allegations made by him in an affidavit filed in the Supreme Court, senior officials said on Thursday.

Bhatt, who accused Gujarat Chief Minister Narendra Modi of misusing the state machinery during post-Godhra riots in 2002, had last month filed an additional affidavit in the Apex Court alleging that Gujarat government was helping the accused in the fake encounter case to prepare their defence.

The CBI on Wednesday questioned Bhatt at his residence for over three hours regarding the Sohrabuddin case and the allegations made by him in the affidavit, officials said.

The CBI also collected documents that Bhatt had obtained from the email account of the Additional Advocate General Tushar Mehta, they added.

The officials said it was apparent from the documents that besides Mehta, bureaucrats attached with the Chief Minister's office, Home department and senior police officers were making attempts to help former Minister Amit Shah, a prime accused in the Sohrabuddin fake encounter case in defending himself.

They said Bhatt could be questioned further, if needed, after examining the documents obtained from him.

The 1988-batch IPS officer was suspended early this month for misconduct by the state government.
