Details emerge after doctor raped and murdered in India as thousands protest

Thousands took to the streets of Kolkata early Thursday to condemn the rape and murder of a local doctor, demanding justice for the victim and an end to the chronic issue of violence against women in Indian society.

The discovery of the 31-year-old's brutalized body last week at a state-run hospital has sparked nationwide protests, with Prime Minister Narendra Modi demanding swift punishment for those who commit "monstrous" deeds against women.

Large crowds marched through the streets of Kolkata in West Bengal to condemn the killing, with a candlelight rally at midnight coinciding with the start of India's independence day celebrations on Thursday.
