Doctors in Kolkata went on strike for weeks in response to the brutal attack.
Tens of thousands of ordinary Indians joined in the protests, which focused anger on the lack of measures for women doctors to work without fear.
While most medics have returned to work, a small group began a hunger strike this month.
The doctors say the West Bengal state government had failed to deliver on its promises to upgrade lighting, security cameras and other measures to protect them.
India’s Supreme Court last month ordered a national task force to examine how to bolster security for healthcare workers, saying the brutality of the killing had “shocked the conscience of the nation”.
The gruesome nature of the attack drew comparisons with the 2012 gang rape and murder of a young woman on a Delhi bus, which also sparked weeks of nationwide protests.
