In a new development after the arrest of former Rajasthan Water Resources Minister Mahipal Maderna, in connection with the missing Rajasthani nurse Bhanwari Devi's case, another key accused has surrendered before the additional chief judicial magistrate in Jodhpur on Friday.

According to media sources, the accused, Sahiram Bishnoi, is believed to have information on how Bhanwari Devi was murdered. He will be in the Central Bureau of Investigation's custody until Jan. 2.

Earlier, in a chargesheet filed against him, CBI claimed that Bishnoi kidnapped Bhanwari Devi and murdered her at the request of Maderna.

Bishnoi went missing a few days after Bhanwari disappeared on Sept. 1, from a village at Bilara and CBI had announced a reward of Rs. 5 Lakh on Bishnoi for providing information about his whereabouts.
