A teenager was killed by her elder brother for talking over the phone for a long time. The incident took place in the southern Indian state of Andhra Pradesh on Friday.

According to local reports, the 17-year-old girl, identified as Lakkana Tanuja, and her family had gone to their hometown to attend a funeral Friday morning. The teen and her brother, however, returned home the same evening as she had to study for her exams. A few hours after returning home, the brother, identified as 19-year-old Ramesh, called his parents and informed them that three men had entered their home through the back door and attacked him before killing his sister.

The brother narrated the incident to the police, who weren’t convinced as Ramesh has not sustained any injuries. He was detained for interrogation during which he confessed to killing his sister. Ramesh told the officers that he and his sister got into an argument about her disobeying him and talking over her phone for a long time.

The argument escalated and the teen slapped her brother. In a fit of rage, Ramesh held Tanuja by the throat. He ended up exerting too much force resulting in the teen’s death. Ramesh was taken into custody and booked with murder.
