The incident took place in Rajpur panchayat's Bahuara village yesterday when apparently fed up with frequent quarrels in the family, Prema Devi (45) consumed poison before forcing her daughters Amrita Kumari (20), Guddan Kumari (18) and Guddu Kumari (16) to consume the substance, Deputy Superintendent of Police (DSP) Mundrika Prasad said.
While Guddan and Guddi died at home, their mother and the elder daughter succumbed to poisoning during treatment at a government hospital late last night, he said.
The bodies have been sent for post-mortem, Prasad said.
