"Women travellers should exercise caution when travelling in India even if they are travelling in a group," the British Government said in an advisory.
The advisory came two days after a 51-year-old Danish women was allegedly robbed and gangraped at knife-point near the New Delhi Railway station.
"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 Polish, German and Danish women travellers have been reported so far in 2014," the advisory said.
"Several recent incidents show that foreign women or expatriates can be the victims of such incidents in India," the advisory said.
