The investigating officer of the case SI Mahfuzur Rahman said officials have been sent to bring the report. After receiving the autopsy report, further action will be taken, the SI added.

Earlier on March 24, Rabi Marandi, 32, a Santal community member of Nimghatu village in Godagari upazila, and his cousin Abhinath, 30, consumed poison in front of Shakhawat Hossain.

They took the decision out of anger "as Shakhawat was not giving them a serial number for a long time to get irrigation water supplied to their fields in Iswarpur", according to their family.

Abhinath died around 9pm after reaching home on March 24 while Rabi died two days later at Rajshahi Medical College and Hospital (RMCH).

Later, the Agriculture Ministry formed a four-member panel to probe the deaths of the two farmers.
