A 51-year-old Danish tourist was robbed and gang-raped at knife-point in New Delhi on Tuesday after she lost the way back to her hotel and stopped to ask directions near the backpacker's area of the city.
A day before, an 18-year-old German charity worker told police in southern India she had been raped on an overnight train by an Indian passenger.
And in early January, a 33-year-old Polish woman was allegedly drugged and raped as she travelled to the Indian capital in a taxi with her two-year-daughter.
"Serious sexual attacks involving Polish, German and Danish women travellers have been reported so far in 2014," the Foreign Office says on its website. "Women travellers should exercise caution when travelling in India even if they are travelling in a group.
"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."
The series of attacks have shone a fresh spotlight on the country's record on sexual violence and its reputation as a dangerous destination for foreign female travellers.
On Friday, police in southern Chennai told AFP that a 22-year-old carpenter arrested over the rape of the German traveller had been remanded in custody for 15 days.
The teenage victim told police she had taken an overnight train on January 10 from the southern port of Mangalore to Chennai and was sleeping on a lower berth when she was attacked by a fellow passenger.
In the Danish gang-rape case, three men have been arrested and police are seeking another five suspects.
In December 2012, a 23-year-old student was gang-raped on a moving bus in the capital in an attack that sent shock waves across the nation. She later died of her injuries.
Though cases of sexual violence against foreigners are not new, the attention on rape in the national media has shone on a light on the frequency of attacks across the country.
Three Nepalese men were handed life sentences last month for raping a US tourist, while six Indians were handed similar punishment last July over the gang-rape of a Swiss cyclist.
