Source : Foreign and Commonwealth Office (FCO) - Women should use caution when travelling in India; reported cases of sexual assault against women and young girls are increasing.
Recent sexual attacks against female visitors in tourist areas and cities show that foreign women are also at risk. British women have been the victims of sexual assault in Goa, Delhi, Bangalore and Rajasthan and women travellers often receive unwanted attention in the form of verbal and physical harassment by individuals or groups of men.If you are a woman travelling in India you should respect local dress codes and customs and avoid isolated areas, including beaches, when alone at any time of day.
Avoid travelling alone on public transport, or in taxis or auto-rickshaws, especially at night. If you have to use a taxi get them from hotel taxi ranks and use pre-paid taxis at airports. Try to avoid hailing taxis on the street. If you are the victim of abuse call “100” for police assistance (“112” from mobile phones).

Take care of your passport and bank cards, particularly when travelling by bus and train. Do not leave your luggage unattended on trains at all. There has been an increase in handbag snatching in Delhi.
Keep a photocopy of your passport, Indian visa and flight ticket separately from the originals when travelling. If your passport is lost or stolen notify the police immediately and obtain a police report.
Be wary of confidence tricksters, particularly in Agra and Jaipur, who promise large amounts of cash for delivery of jewellery abroad in return for an initial deposit. The jewellery is worthless and the deposit, often amounting to thousands of pounds, is lost.(source:4hoteliers.com)
