Five members of a family were killed with sharp-edged weapons in Khevrajpur village in the district, police said on Saturday.
While the Samajwadi Party (SP) attacked the Yogi Adityanath government saying that Uttar Pradesh is "immersed in crime", Bahujan Samaj Party (BSP) chief Mayawati demanded a thorough probe into the incident.
The Tharwai Police Station received information around 5.30 a.m. that four-five people had been spotted dead in a house and on reaching there, police found the head of the house, Rajkumar (55), his daughter Manisha (25), his wife Kusum (50), his daughter-in-law Savita (30), and granddaughter Mitakshi (2) dead, Senior Superintendent of Police (SSP) Ajay Kumar said.
The incident occurred on Friday night when Rajkumar's son Sunil was not in the house. He had gone to attend a wedding.
The SSP said that prime facie it appears that the deceased were hit with a stick or some blunt weapon and there were injury marks on the head also.
How the killings took place and other details will be known only after the post mortem of the dead bodies, the SSP said, adding it will be videographed so that no evidence is left out.
A fire in the bedroom of the house was extinguished by the fire brigade, he said.
Family members have reached here and talks are being held with them.
A case has been lodged at the Gangapar Tharwai Police Station and seven teams have been formed to look into the whole matter, the SSP said.
A dog squad and forensic team have reached the spot and evidence is being collected after inspecting the spot, police said.
Reacting to the incident, SP president Akhilesh Yadav said, "Under the BJP 2.0, U.P. is immersed in crime. Today's testimonial", and attached a news report of the killing.
BSP president Mayawati said, "The news of the brutal murder of five members of a family in Prayagraj is very sad, condemnable and worrying . The government should go to the bottom of the incident and ensure that strict legal action is taken against the culprits."
Earlier, on April 15, in Khagalpur village of the Nawabganj Police Station area of the Gangapar area here, four members of a family were murdered with sharp weapons.
