'A decent girl won't roam around at 9 o'clock at night,' said Mukesh Singh, one of four men condemned to death for the hideous sex attack that shocked the world two years ago.

'A girl is far more responsible for rape than a boy. Boy and girl are not equal. Housework and housekeeping is for girls, not roaming in discos and bars at night doing wrong things, wearing wrong clothes.

'About 20 per cent of girls are good.'

The depraved murder of Jyoti Singh in December 2012 sparked revulsion across the world as well as a wave of protests in India, where people demanded a change in attitudes towards women.

The 23-year-old student had been returning from a cinema with a male friend on a Sunday evening when she accepted a lift from the off-duty charter bus.

Once inside, bus driver Mukesh Singh, his brother Ram, gym instructor Vinay Sharma, 20, bus cleaner Akshay Thakur, 28, fruit-seller Pawan Gupta, 19, and an unnamed teenager subjected to a horrific rape.

She died a fortnight later after suffering terrible injuries to her abdomen, genitals and intestines.

Jyoti's death sparked a period of deep soul searching in India, where equal rights for women are enshrined in the constitution but rarely effective in practise.

'Before, they would rape and say, "Leave her, she won't tell anyone." Now when they rape, especially the criminal types, they will just kill the girl. Death.'

Mukesh Singh and his accomplices treated Jyoti no better. After luring her aboard the bus, they took turns raping her and beat her with an iron rod when frantically tried to fight them off.

Two blood stained metal rods were later retrieved from the bus; medical staff confirmed that 'it was penetration by this that caused massive damage to her genitals, uterus and intestines'.

And after the rapists had enough, rather than 'dropping her off' they threw her and her friend from the moving bus. Mukesh Singh then allegedly tried to run them over, but her friend had enough strength left to pull Jyoti out of the way.

Despite efforts to get her the best medical care, even flying her to a hospital in Singapore, Jyoti died 13 days later, having suffered brain damage, pneumonia, and abdominal infection.

Doctors had already been forced to remove most of her intestine.
