The Supreme Court will on September 19 hear Siwan native Chandrakeshwar Prasad's plea challenging the Patna high court's order of granting bail to gangster-turned-politician Mohammad Shahabuddin.

Prasad earlier in the day had filed the petition in the apex court.

He said he would also request for a Central Bureau of Investigation inquiry if need arises.

"You should either keep such a person out of Bihar or give him capital punishment. We would request the CBI too," said Prasad.

"I did not ask for chanda as Shahabuddin is saying. I am just asking for government help. We are old and are surviving on medicine. We want compensation," he added.

Senior advocate Prashant Bhushan has also filed a petition in the top court for the cancellation of bail granted to Shahabuddin, who walked out of the Bhagalpur jail last week.

Shahabuddin, who had been in jail for more than 10 years in connection with multiple cases, was granted bail by the Patna high court on September 7 in connection with the murder of a the third son of Prasad who witnessed the killing of his two brothers in Siwan.
