NEW DELHI — One of the five men charged with gang-raping and killing a woman is a minor, his lawyer said Monday as he demanded an age-determination test in what could be a tactic to delay the case from being tried in a fast-track court.

The five charged in last month's attack of the 23-year-old student in a moving bus in New Delhi would face a possible death penalty if convicted. A sixth suspect says he is 17 years old, and if he is tried in a juvenile court he would face a maximum sentence of three years in a reform facility.

The rape of the woman, and the brutal beating that led to severe organ failure, has set off an impassioned debate about what India needs to do to prevent such tragedies. Protesters and politicians have called for tougher rape laws, police reforms and a transformation in the way the country treats women.
