A complaint was lodged against controversial Rashtriya Janata Dal parliamentarian Mohammad Shahabuddin on Saturday for threatening to kill Siwan jail superintendent Lalan Kumar Sinha.

"The parliamentarian used expletives against jail superintendent Lalan Kumar Sinha and threatened to kill him when he read out the production warrant against him in his cell," Superintendent of police Sunil Kumar told PTI.

A case for obstructing a public servant in performing his duty and issuing threats has been registered with the town police station against Shahabuddin, he added.

Jail sources told PTI that when Sinha approached the parliamentarian, who is suffering from a spinal problem, to take him in a wheel chair before the court, Shahabuddin refused to go.

He demanded that a stretcher be brought. When it was brought, he again refused and demanded one with an iron sheet because of his spinal problem. By the time that one arrived, the court had risen for the day.

A special building has been designated as court in the divisional jail premises for the last three days to start trial proceedings against Shahabuddin in connection with six of the 40 cases against him, including that of sedition.

The cases relate to seizure of firearms, ammunition with Pakistan Ordnance Factory markings and attempt on the life of former Communist Party of India (Marxist-Leninist) legislator from Mairwa Satyadev Ram.

Shahabuddin was transferred from Bhagalpur Central Jail to Siwan on May eight. He had last month reportedly manhandled the jail superintendent when he objected to the presence of six under trials in his cell.
