New Delhi:The Supreme Court on Monday asked the CBI to respond on a bail plea by former Rashtriya Janata Dal MP Rajesh Ranjan alias Pappu Yadav undergoing life imprisonment in  Ajit Sarkar murder case.

Pappu Yadav was punished for conspiracy and murder of Communist Party of India-Marxist MLA and trade union leader Ajit Sarkar.

A Session Court had given life term to three accused in the case. It should be noted that Pappu Yadav had applied for bail in the Patna High Court which was turned down by it. Following which he moved the Supreme Court for securing his bail.

The Apex Court Bench of Justice Altamas Kabir and Justice S.S. Nijjar issued notice to the Central Bureau of Investigation (CBI) after senior counsel RS Sodhi, appearing for Pappu Yadav, told the court that his client was still in jail while two other convicts Anil Kumar Yadav and Rajan Tiwari who had actually pulled the trigger had been granted bail.

The court gave the CBI two weeks time to respond to the notice.

Two co-accused granted bail earlier were Anil Kumar Yadav and Rajan Tiwari. The court was told that Pappu Yadav had already undergone 10 years' imprisonment and was very sick, who needed an urgent treatment

Sodhi told the court a medical board, that examined him, said that he was suffering from an ailment for which there was no treatment in Patna and he needed to be treated in Delhi.

Assailing the Patna High Court verdict of Oct 21, 2011 which rejected Pappu Yadav's bail plea, the court said that he would have to bear the cost of his treatment on his own.

While hearing his bail plea, the SC issued a fresh notice to CBI on Monday.
