The incident took place in a slum in the steel city of Rourkela, about 514 km from state capital Bhubaneswar Saturday night. The matter only came to light when the husband of the deceased lodged a complaint at the Udit Nagar police station the next day.

Additional District Superintendent of Police Sudarsan Sethi said 24-year-old Sanjay, an alcoholic, would often extract money from his 46-year-old mother Salmi Lakra to buy liquor.
