A 60-year-old woman was beaten to death in Bihar's Nawada district allegedly by neighbours accusing her of practising witchcraft, the police said on Tuesday.
The incident occurred at Kalliyatand Tola of Taraun village under Kauwakol police station area on Monday night, hours after the death of a 12-year-old boy who was ailing for a long time.
Suspecting that the boy died because of witchcraft performed by the victim, identified as Chinta Devi, her neighbours lynched the elderly woman, police said.
Her daughter has lodged an FIR against four persons.
Of the four, a man and his son were arrested, Superintendent of Police Hari Prasath S said.
The death of the arrested man's 12-year-old son led to the attack on Chinta Devi.
