A senior police official said the family is suspected to have consumed poison in their food last night. The family was apparently facing financial problems, he said, adding that they were inquiring into all aspects.
According to the police, the family's head, identified as Balaraju, belonged to Munigadapa village in Jagdevpur mandal of Siddipet district.
He was working as farm labourer and taking care of the poultry there at Rajapet village, which comes under the jurisdiction of Rachakonda police commissionarate.
"Most probably we are suspecting food poising. Prime facie, we don't find any foul play like homicide. We cannot come to a conclusion until we get the autopsy report," the police official said.
A case has been registered and an investigation is on, he added.
