Police in India's eastern city of Kolkata have fired tear gas and water cannons to disperse thousands of protesters demanding justice for the rape and murder of a trainee doctor at a government hospital earlier this month.
The discovery of the 31-year-old's body sparked nationwide outrage over the crisis of violence against women.
On Tuesday, thousands of people marched to a government building in Kolkata, demanding the resignation of West Bengal Chief Minister Mamata Banerjee.
A hospital volunteer has been arrested in connection with the crime, which has now been handed over to India's Central Bureau of Investigation (CBI) after criticism of the local police's slow progress.
Protesters shouted slogans and clashed with the police, who used batons to disperse the crowd.
Namita Ghosh, a college student involved in the protest, told the AFP news agency that the crowd wanted to stage a “peaceful protest” before the lathicharge.
At least 100 protesters have been arrested for “inciting violence”, a senior police official said on condition of anonymity.
Protests have been going on since the killing on August 9. The largest was the Reclaim the Night March, which saw tens of thousands of women across West Bengal on 14 August to demand “freedom and freedom to live without fear”.
But since then, some protests have turned into chaotic political rallies, with police clashing with protesters from the ruling Bharatiya Janata Party (BJP) angry with the state government.
The BJP, led by Prime Minister Narendra Modi but an opposition party in West Bengal, has accused Ms Banerjee's government of promoting an unsafe environment for women, which it claims is Enables crimes like the murder of a doctor.
Her semi-naked body was discovered in a seminar hall of RG Kar Medical College where she had gone to rest during her shift.
The Supreme Court of India has said that this incident… “Shocked the nation's conscience” and criticized the authorities for their handling of the investigation.
Ms Banerjee's government has announced a number of measures to protect women in the workplace, including designated retiring rooms and CCTV-monitored “safe zones” in state-run hospitals.
Since the woman's death, more rape cases have hit the headlines in India and Prime Minister Narendra Modi has said that “cruel behavior against women should be punished severely and swiftly”.
