An international rights group has called on India to prosecute security forces it says have committed torture.
Human Rights Watch said a recent video showing Indian border guards beating a Bangladeshi proved the forces were "out of control".
Eight Border Security Force (BSF) guards were suspended in connection with the incident.
The Indian home ministry said it could not comment until it had studied the Human Rights Watch report.
No charges have yet been filed and the BSF says it is investigating what it has called a "despicable" incident.
The mobile phone footage appears to show soldiers stripping and assaulting a suspected cattle smuggler.
The Bangladeshi government lodged an official complaint with India after the video was shown.
"The Indian government is well aware of killings and torture at the border, but has never prosecuted the troops responsible," said Meenakshi Ganguly, South Asia director at Human Rights Watch.
"Secret proceedings and suspensions or transfers won't end the abuses. Torture is a serious crime that should be prosecuted in the courts," said Ms Ganguly.
The BSF insists that after any incident an inquiry takes place and action is taken.
The home ministry said it had not seen the report yet and would respond only after studying what it said.
