The decomposed body of a 50-year-old woman, who was allegedly raped and killed by a person, was found in Jharkhand`s Sahibganj district, police said on Sunday.

The accused was arrested after the son of the deceased woman lodged a complaint with the Barhait Police Station, alleging that her mother was raped and throttled to death, a senior officer said.

The woman, who belonged to a particularly vulnerable tribal group (PVTG), was missing since Thursday and her body was recovered by villagers on Saturday near a deserted place in the hills in Chihad Pahad, he said.
