Sacked Rajasthan minister Mahipal Maderna, arrested in Bhanwari Devi abduction case, was brought to Delhi on Sunday by the Central Bureau of Investigation for further questioning in the case.

59-year old Maderna was arrested on Friday in Jodhpur by the CBI along with Parasram Bishnoi, the brother of Congress MLA Malkhan Singh, hours after it filed charge sheet against three other arrested accused.

He was sent to CBI custody till December 9 by the Jodhpur court. Agency sources said Maderna was moved to the national capital for further questioning in the case.

The CBI officials had on Saturday alleged that they were being threatened. Bhanwari, posted as an auxiliary nurse midwife at a sub- centre in Jaliwada village went missing on September 1 after a CD allegedly showing Maderna in a compromising position with her was circulated in political circle.

On the other hand, there is no information on the whereabouts of Indra Bishnoi, sister of Malkhan Singh Bishnoi and a key witness in the Bhanwari Devi case.

Maderna, who represents Osian assembly constituency, was sacked from the Cabinet on October 16 by Chief Minister Ashok Gehlot after his name cropped up in the case.
