Indian authorities have charged five men with the kidnap, gang-rape and murder of a woman in Delhi last month.
The 23-year-old was travelling on a bus when the men beat her and her companion with iron bars, raped her for nearly an hour and then threw them out of the moving bus into the street, say police.
The attack has sparked mass protests in India and there have been calls to improve safety for women.
The BBC's Yogita Limaye took a bus ride in Delhi and asked women how they feel travelling on the city's public transport system.
