BDR pushed back six Indian tribals including two women who had mistakenly crossed the Indian territory and entered Bangladesh on June 21, they said.
Border Security Force personnel received them at the Muhurighat checkpost in South Tripura district.
The tribals complained that Bangladeshi villagers detained them, beat them up and then handed over to police.
However, they told the police that BDR and Bangladesh police behaved well with them.
Tripura has 856 km-long porous border with Bangladesh.
