Safety and security
Crime
Women travellers should exercise caution when travelling in India even if travelling in a group. 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. Serious sexual attacks involving foreign nationals have been reported. In January 2015, a Japanese woman was kidnapped and sexually assaulted close to Bodh Gaya and a Russian woman was seriously assaulted by an auto-rickshaw driver in the Vasant Kunj area of New Delhi. In July 2016 an Israeli national was sexually assaulted by a number of men while travelling in Manali. In March 2017, an Irish woman was raped and murdered while on holiday in Goa. In April 2018, a Latvian woman was sexually assaulted and strangled in Thiruvallam, Kerala.
