The nun was raped on August 25, 2008, two days after ethnic riots broke out in Kandhamal, 210 km west of Bhubaneswar, following the killing of Hindu leader Laxmananda Saraswati.
Saraswati, who had been running a campaign to convert Christians into Hindus, was killed by Maoists, but Panas — Dalits converted to Christianity — faced the fury of Hindu nationalist groups.
Thirty-eight people were killed and thousands displaced in the riots. The nun had alleged she was attacked, gang-raped and paraded semi-naked through the streets.
