New Delhi: The CBI on Tuesday questioned former UP Minister Babu Singh Kushwaha here in connection with alleged swindling of funds in the National Rural Health Mission and related three murders of top health officials.

Kushwaha, once a close-aide of Chief Minister Mayawati, arrived at CBI Headquarters this morning where questioning started about his tenure as Family Welfare Minister and alleged irregularities in the funds during that period, sources said.

The agency had summoned Kushwaha and former Health Minister Anant Mishra here for questioning in connection with the multi-crore NRHM scam and three murders of health officials which had led to state-wide furore over allegation of rampant corruption in execution of the central scheme, they said.

The Ministers were asked to appear before the agency on Tuesday and on Wednesday for questioning which would also cover murder of two CMOs and deputy CMO Y S Sachan who was found dead inside a district jail, they said.

The Lucknow bench of the Allahabad High Court had on July 27 directed CBI to probe the murder of the two CMOs and also into the alleged irregularities in implementation of the National Rural Health Mission (NRHM) within three months.

The CBI had started probe into the alleged irregularities in spending of Rs 10,000 crore allocated to Uttar Pradesh as central funds under NRHM, after registering five preliminary enquiries following orders of the High Court.

The agency has constituted a special investigating team comprising 26 officers, including five Superintendents of Police under the overall supervision of Additional Director, Joint-Director and two DIGs.
