Dozens of people gathered at the Jantar Mantar in New Delhi on Monday to protest the rape and brutal murder of a Hyderabad veterinarian last week, which shook the country.

Around 40-50 protesters took to the streets and were seen wearing black bands and carrying placards that read 'we want justice' and 'hang the rapists'.

The woman, who worked in a state-run hospital, was raped and killed by four accused — all lorry workers — on the city's outskirts.

Her charred body was found under a culvert in the city's Shadnagar area on Thursday and the accused were arrested a day later.

Amrita Dhawan, the organiser of the protest said, 'I am organising this protest not as a politician but as a member of the civil society who is concerned about what is happening. Why did we need another Nirbhaya to talk about how unsafe women are?'

She said the judicial system has to ensure speedy justice so that victims' families get some solace.

'Nirbhaya's rapists are still in jail and have not been hanged. Those in jail are living their life, getting food and sleep but what about the families of the victims, whose lives have been ruined forever,' she said.

Cries of 'we want justice', 'we are ashamed that your killers are alive' resonated through the air at the protest as people holding placards demanded justice for the Hyderabad victim and other women who face such crimes.

Aditi Purohit, a student of Delhi University's Hansraj College, broke down while shouting the slogans.

'This is my first time in a protest. I am here because just like a woman who stays in Delhi away from home, the issue affects me and my family.'
