Sacked Rajasthan Minister Mahipal Maderna was today arrested by the CBI along with the brother of a ruling Congress MLA in Bhanwari Devi abduction case.

Maderna, who was sacked from Ashok Gehlot cabinet on October 16 after his name cropped up in the case, and Parasram Bishnoi, brother of ruling party MLA Malkhan Singh, were taken into custody this evening after another round of questioning.

The arrest came after the agency filed its first charge sheet in the sensational case in a court in Jodhpur, charging the three accused – Shahabuddin, Baldev Jat and Sohan Lal, who are in judicial custody, with entering into the conspiracy to abduct the 36-year old nurse with an intent to murder her.

In its charge sheet filed before Judge Jagdish Jyani, CBI has accused them of abducting the nurse with an intent to kill, criminal conspiracy and various sections of SC and ST Act.

The agency in its charge sheet named Maderna and absconding suspect Sahiram.

The agency, which is yet to trace the nurse who went missing on September 1, filed the charge sheet in the case as the 90-day deadline following the arrest of the three accused was about to expire next week.

The court also gave permission to the CBI today to record the voices of Sohan and Shahbuddin to match them with those in audio clips which are in public domain now.

The CBI had moved an application yesterday seeking the court's permission to check the authenticity of the video clips which was granted today.
