Special Public Prosecutor Raja Thakre filed a supplementary chargesheet in the court. This chargesheet relates to accused Kamal Ansari's arrest in Madhubani, Bihar when the police allegedly found RDX in his house. The ATS, which is investigating the case, had moved the Supreme Court, praying the matter be clubbed with the 7/11 serial blasts case. On April 5, the SC clubbed the matters and ordered that the 7/11 case and Ansari's case are part of the same conspiracy.
