The police are suspecting it to be a case of homicide.
Four members of a family were found dead at their home in Hyderabad's Tarnaka area on Monday.
The man, Vivin Pratap, was working as a design engineer with Mercedes-Benz in Chennai and his wife Sindhura, was recently transferred to Hyderabad as a manager at Bank of Baroda.
The man's 65-year-old mother, Jayathi, and 4-year-old daughter, Adhya, were also found dead.
The police are suspecting it to be a case of homicide. “Domestic quarrel and differences between the couple over shifting to Chennai possibly led to the extreme step,” Osmania University police station inspector L Ramesh Naik told NDTV.
Forensic and post-mortem reports are awaited to confirm the exact cause of death.
