"Today we remember the braveheart who died after fighting for her life for several days," said Radhika, who has been joining protests at Jantar Mantar since Dec 20.
People lit candles and marched towards Parliament Street. However, they were prevented by policemen from moving beyond Jantar Mantar.
"We are holding a peaceful protest which we will continue till there is justice for the woman who has died. We want justice, and we want amendment in laws dealing with rape," said Nupur Sharma, a college student.
Among the protestors was former woman Indian Police Service officer Kiran Bedi.
Bedi demanded a social audit of the police forces and the judiciary.
"We should demand that gender sensitivity be taught in schools and colleges," Bedi said.
"We should teach our daughters to be brave," Bedi said.
She said there is a need for citizen-social audit of systems.
"Through this, I mean annual performance check of local police station and court by a team of system experts," she said.
The 23-year-old student of physiotherapy died Dec 29 in a Singapore hospital after battling for life for over a week after being brutally raped by six men in a moving bus Dec 16.
