Four people of senior Congress leader Sircilla Rajaiah's family, including his daughter-in-law and three grandchildren were burnt alive after a fire broke out at the former MP's house in Warangal on Wednesday.
According to a report in NDTV, a gas cylinder leak is supposed to have triggered the fire which killed Sarika and her three sons - Abhinav, Ayan, Sriyan. The police also suspect that family issues could be behind the deaths, as Sarika has attempted suicide before.
This comes on the day Sircilla planned to file his nomination papers for the Warangal Lok Sabha by-election for the Congress.
Sircilla's daughter-in-law had married his son in 2002 but the family has witnessed turbulent times. Sarika had earlier filed a case of dowry and even staged a sit-in outside her father-in-law's house.
Sircilla Rajaiah won the Warangal MP seat in 2009 elections as a Congress nominee, but lost it in 2014 elections to Kadiyam Srihari, who was later promoted to the post of Deputy Chief Minister of Telangana.
The Congress is also planning to change its nominee for the elections. A senior Congress leader told The Hindu that the party was now considering the names of former Union Minister Sarvey Satyanarayana, former Wardhannpet MLA Kondeti Sridhar, former Minister G.Vijayarama Rao and Congress leader R. Pratap.
The police have registered a case and have detained Sircilla, his son Anil and wife Madhavi. The bodies of the four deceased, have been moved to a hospital and further investigations are on.
