45-year-old Lalpari Devi of village Naubatpur village in Patna had on Thursday gone to Adalchak village for treating one Manorama Rai, who was suffering from a mental ailment, police sources said on Friday.
As Manorama's condition deteriorated during treatment, her husband Ramayodhya Rai got angry with Lalpari and tied here to a tree with the support of her neighbours and mercilessly beat her up.
He then tonsured her head and smeared her face with limestone.
Police soon reached the scene and rescued Pari. She was admitted to a hospital from where she was discharged Friday morning.
Police lodged an FIR and arrested Ramayodhya Rai.
