A South Korean student has been molested on a bus in eastern India, in the latest of a disturbing trend of sexual abuses in the country.

The 20-year-old, accompanied by two South Korean women and a man, was aboard a crowded bus in Kolkata early Monday when three men pursued her and allegedly “grabbed her buttocks and breasts”, police official Subhendu Barik told AFP. The bus driver reportedly avoided to intervene.

The woman jumped off the bus and ran towards a traffic official who helped catch one of the three men, identified as Sujit Mondal, and brought him to a nearby police station.

The arrested man later appeared in court and was remanded in police custody until April 2, Kolkata deputy police chief Sumanjit Roy told AFP.

Police said they were searching for the two other men accused of molesting the South Korean woman.

Monday’s incident is the third time in just 10 days that a foreigner has been the victim of sexual abuse in India, raising fears for the safety of women in the country.

A British tourist jumped off a hotel balcony in the Taj Mahal city of Agra in a bid to escape an alleged sexual assault. Earlier this month, a Swiss cyclist was gang-raped in Madhya Pradesh in front of her husband, who was tied up.
