Women's groups and citizens are holding vigils across the Indian capital Delhi in memory of a student who died after she was gang-raped a year ago.

Her family, which is planning a small memorial service, told the BBC that they wanted to keep her memory alive as long as possible.

A small vigil will also be held at the bus stand where she boarded the vehicle on which she was attacked.

The rape shocked Indians and prompted protests across the country.

It also led to the introduction of tougher laws on rape and special fast-track courts to try suspects.

The 23-year-old medical student was attacked on a moving bus while she was returning home after watching a film with a male friend who was also beaten up.

Four of the six attackers were given the death penalty in September. A fifth adult suspect was found dead in his prison cell earlier this year before he could be tried.

The sixth member of the group, a juvenile at the time of the crime, is serving a three-year sentence.

On Monday, exactly a year after the attack, Mumbai-based theatre and protest music group Swaang and Delhi-based cultural group Majma organised "a show of strength by the citizens of Delhi - women and men - to claim back the streets of Delhi".

Well-known musicians were to perform on a moving trailer, retracing the fatal journey of the victim, through the streets of the capital, the organisers said.

The journey will begin at the mall where the woman watched the film and conclude at the road crossing in the Mahipalpur area where she and her friend were thrown out of the bus.

Dozens of people have also gathered at Delhi's Jantar Mantar monument to remember the victim.

Although India has tightened its anti-rape laws and society is more openly discussing cases of violence against women, correspondents say women across India still live with the daily fear of sexual assault and victims still often have to deal with police apathy.
