Five persons, including two children and their father died on Thursday here in a village after drinking tea allegedly spiked with a chemical, police said.

Shivanandan (35), his sons Shivang (6) and Divyansh (5), his father-in-law Ravindra Singh (55), and neighbour Sobran (42) fell seriously ill after drinking tea made in his house in Nagla Kanhai village, Superintendent of Police Kamlesh Dixit said.

All of them were taken to the district hospital where doctors declared Ravindra, Shivang, and Divyansh brought dead, the SP said.

Sobran and Shivanandan were referred to Saifai in a serious condition where they both died later, he said.

Dixit said that preliminary investigation has established that Shivanandan's wife Ramamurthy mistook the medicine sprayed in the paddy for tea leaves and put it in the tea which made it toxic.
