The Director General of Border Security Force (BSF) has been asked to submit a detailed inquiry report on the incident.
The BSF men on duty near the border area of BOP Bhangamura under 31 battalion BSF Tripura frontier observed 30-40 smugglers including men and women, trying to smuggle cattle from India to Bangladesh through unfenced gap.
The BSF challenged them and fired two warning shots in the air to disperse the smugglers, but the smugglers did not pay any heed.
They encircled the BSF and attacked them.
Sensing their life in danger, the BSF fired in self-defence, in which three smugglers died.
