The 29-year-old was called to Begumpet police station on Friday evening, after his father-in-law Jayaram complained that he was teasing and harassing his younger daughter Radhika (16).

On returning home, Ramu complained of giddiness and was taken to a physician in Pattigadda, who advised him rest. He again had same complaint and was taken to KIMS Hospital, where he was pronounced dead late on Friday night. Doctors said the cause was unknown.

The police said Ramu did not have food and rest for three days due to the problems created by his actions in the family. They also claimed that the man was a chronic diabetic.
