\Police began its investigation after former palace manager of Odisha's Gajapati dynasty was found dead.
A former palace manager of Odisha's Gajapati dynasty was found dead along with two of her siblings, inside a house at Parlakhemundi in Gajapati district on Sunday, police said.
The deceased were identified as Anang Manjari Patra, the former manager of the Parlakhemundi palace, her brother Sanjay Patra who was personal assistant of Maharaj Gopinath Gajapati Narayan Deb and their sister Bijaylaxmi Patra.
Another sibling identified as Santosh Patra alias Tulu was found in a serious condition in the house, Amitabh Thakur, Inspector General, Southern Range, said. He has been taken to MKCG Medical College Hospital in Berhampur.
Mr Thakur said the victims were under police scanner after allegations of confining the Maharaja were made against them. Anang Manjari and her brother Sanjay Patra were accused of keeping Maharaj Deb under house arrest and not allowing anyone to meet him.
The police had begun investigation into the allegation two days ago, Mr Thakur said.
While the bodies of Anang Manjari and her sister Bijaylaxmi were found in one room of their house, Sanjay's body was found hanging from the ceiling, the police said. Gajapati district Superintendent of Police Sushil Panigrahi said, "It appears to be a case of suicide."
The IG, however, said that the cause of the death could be confirmed only after getting the postmortem report.
