A case was registered and Deepak was arrested, she said.
During interrogation, the accused told police that he suspected his mother to be an "illicit relationship" with someone, the officer said.
However, preliminary investigations revealed that Deepak had demanded money from his mother to perhaps buy liquor. But when she refused, a quarrel broke out between the two following which he slit her throat with a kitchen knife, police said, adding further investigation is going on.
