Aseemanand is main accused in several blasts in Muslim vicinity including the Dargah of Ajmer. He is currently in custody of Rajasthan ATS
Aseemanand, who was produced in the court along with two other accused Mukesh Vasani and Harshad Solanki, gave the letter to Chief Judicial Magistrate R L Moond on Tuesday.
The court also extended the judicial custody of the three accused till March 1. The ATS will produce another accused Bharat Bhai in the court on February 18 after his remand is over.
The case of other three accused Devender, Lokesh Sharma and Chandershekhar is slated for hearing on 19th February in the court of District Magistrate.
The local court is hearing the blast at the dargah of Khawaja Moinuddin Chishti in Ajmer that took place in 2007 in which three people were killed and several other were injured.
Meanwhile interrogation of Swami Aseemanand and Bharat Bhai Rateshwar by the ATS has shed more light on the murder of Sunil Joshi, a key suspect of the 2007 Ajmer Dargah blast.
While Aseemanand said he had warned Sunil Joshi about the threat to his life, Rateshwar implicated RSS leader Indresh Kumar in the murder case.
Among many revelations, Aseemanand has reportedly told the ATS about two Muslim boys with whom Joshi used to hang out.
