Rajan Yadav, the main accused led the charge. Yadav was given a life time imprisonment in kidnapping case, he along with other inmates of the jail wanted the doctor to issue them a fake certificate, so that they would not be shifted to other jail.
The doctor was killed after he refused to issue fake certificate.

They are convicted criminals and we will try to charge sheet them as soon as possible. We will ensure a speedy trail in the case and see to it that the criminals are brought to justices," said K S Anupam, SP, Gopalganj jail.
