Vishnoi, representing Luni assembly constituency, was evading questioning for the past few days and was arrested by the agency on Monday night when he appeared before the CBI. He was produced before the special CBI court on Tuesday which remanded him to CBI custody till December 28. Bhanwari Devi, posted as an auxiliary nurse at a sub-centre in Jaliwada village in Jodhpur, went missing on September 1.
Her husband Amar Chand, who is also in CBI custody, had alleged she was abducted at the behest of Mahipal Maderna who was later sacked from the Ashok Gehlot ministry.
The CBI had arrested Amar Chand as he was not cooperating with the agency during questioning and kept changing his statement leading to suspicion of his involvement in the alleged abduction of his wife. Shahbuddin, Baldev and Sohan Ram are the other accused who are behind bars in connection with the case. Two more accused, Sahiram and Bishnaram Bishnoi, are absconding.
