I don't understand what you are writng - WHO raped a boy and WHO got 3 years for it?
The four men were sentenced to death, along with two members of the panchayat. It transpired that the allegation against Shakur, was made up in an attempt to hide the fact that it was her brother who had been raped by men from the Mastoi caste.
Three men were later sentenced to three years in prison for that crime.
