The commission, in a notice issued on July 21, asked the Indian home secretary and director general of police of West Bengal to submit the requisite information and report on the incident in six weeks.
The commission took the move after the victim of the rape, Kalyani Rani Mandal, widow of slain Rabindranath Mandal, lodged a complaint with it through the Global Human Rights Defence on July 21.
Rabindranath and Kalyani of the village Bolabari in Ashashuni, Shatkhira, were arrested by BSF personnel when they were returning home from Nadiya district of West Bengal on 23 April, 2009.
The BSF stopped the couple near pillar 4 of the Satkhira-Lakshmidar i border and bludgeoned Rabindranath to death. After killing the man, they tortured and raped Kalyani.
Bangladesh's rights watchdog Odhikar conducted a fact-finding mission regarding the gory incident.
During the mission, Odhikar talked with Kalyani, relatives of slain Rabindranath, witnesses, doctors treating the victim at hospital, members of the law enforcing agencies and local government representatives in Satkhira.
The mission came to know that after arresting the couple, the BSF men hung Rabindranath on a tree and beat him to death and then gang-raped Kalyani.
The BSF men left the body of Rabindranath and injured Kalyani near pillar 4 of the Satkhira-Lakshmidar i border.
The couple had gone to India six months before the incident for treatment.
