Police say they have arrested three Indians for allegedly gang raping a young Japanese research scholar in a Buddhist pilgrimage center in eastern India.

Police officer Akhilesh Singh says police are looking for two more suspects who also allegedly kept the Japanese woman as a hostage for nearly two weeks in Bodh Gaya, a town nearly 130 kilometers (80 miles) south of Patna, the capital of Bihar state.

She managed to escape from their captivity on Dec. 26 and reached Kolkata, once known as Calcutta, where she was based and filed a police complaint.

India has a long history of tolerance of sexual violence. But a series of high-profile rape cases have triggered a strong public outrage in recent years, leading to tough anti-rape laws.
