Dehradun: Ruling out any criminal conspiracy in the death of Swami Nigamananda during his hunger strike in Haridwar, the CBI filed a closure report in the case on Wednesday here. The investigating agency cleared that the Swami was not poisoned but died due to malnutrition following three months long fast.

Swami Nigamananda, who was fasting to oppose illegal mining, was forcefully admitted to Haridwar District Hospital by the district administration. Doctors referred Swami to Doon Hospital seeing his critical condition. Thereafter he was transferred to Himalayan Institute situated in Jolly Grant where he died on June 13.

Matri Sadan Ashram, to which Swami belonged, filed a complaint in Haridwar police station alleging that he was poisoned. Chief Medical Officer (CMS) of the Haridwar District Hospital, Dr P K Bhatnagar and Gyanesh Kumar (stone crusher) were accused of poisoning Swami.

The CBI took over the case on August 18 and carried out detailed investigations interrogating all suspects including the hospital staff and recorded all the statements.

CBI re-conducted the post mortem. A special team was formed, including doctors from All India Institute of Medical Sciences (AIIMS), to look into the investigations.

After four months of probe, the CBI submitted closure report in the case.
