DHAKA: Five men have been arrested in India charged with kidnapping and repeatedly raping a Japanese student.

Police in the eastern city of Calcutta say the assaults took place over a period of more than a month from 23 November and in at least two locations.

They say an organised gang is suspected of targeting single women tourists.

Increasing numbers of rape cases are being reported and highlighted in India, prompting widespread outrage.

Pallav Kanti Ghosh, a Calcutta police commissioner, told BBC Hindi that two of the men - said to be brothers - approached the 23-year-old victim as tourist guides after she arrived in the city and checked into a hotel in an area popular with foreign tourists.
