A man was arrested late Saturday on suspicion of raping a Japanese tourist the previous day in the famed beach resort of Kovalam in the southern Indian state of Kerala, police said.
According to the police, the woman was hospitalized after the attack, which occurred in her room in a small hotel in the town famous for its crescent beaches.
"The woman called the police and was found bleeding when we reached her at the crime spot," an investigation officer said.
The accused is the 25-year-old son of the owner of a handicrafts shop at Kovalam beach, the officer said.
The Japanese Consulate-General in Chennai said the woman is conscious and able to communicate.
There is concern over increasing sexual violence against women in India, with attacks against foreign travelers also on the rise.
Last year, six men were arrested for the gang rape of a young Japanese woman in Jaipur, a popular tourist destination in the western state of Rajasthan.
