A 21-year-old man from Karnataka's Haveri district was arrested on Saturday after he confessed to raping and killing his mother when he found out about her relationship with another man.

The family of the victim alleged that the 21-year-old did not approve of his mother's relationship and accused her of having multiple affairs with other men. An argument regarding the same apparently led to his brutal act on the evening of November 12. "The woman had allegedly told her son that she wanted to be with her boyfriend. This had led to a huge argument," the police reportedly said. On Thursday evening, the woman was on her way home from work when her son stopped her and forced her to consume alcohol. He then took her to a nearby field where they got into an argument and he subsequently raped and strangulated her to death. The victim's sister, who located her body the next day, registered a complaint with the police. "My daughter and I began suspecting that he had something to do with her death because when we found her body, her clothes were in a disarray. We had asked him many times on Friday (November 13) about my sister's whereabouts and he lied repeatedly. When I filed the complaint with the police, I had mentioned his name, when they asked me if I suspected anyone's involvement," the woman's sister informed TNM.

"She was seeing one man but you know how people talk about women who have affairs after their husbands die. My nephew used to verbally abuse her when people began talking," the woman further added, according to the report. On Saturday evening, an FIR was registered against the 21-year-old man under sections 376 (rape) and 302 (murder) of the Indian Penal Code. The accused has been remanded to judicial custody.
