Reena Shukla (35), her daughter Chhavi (15) and three of her relatives were found murdered at Virendra Nagar area here yesterday, they said.
The killing was the fallout of an alleged illicit relationship between the accused Ritesh Dixit and Reena, district Additional Superintendent of Police (ASP) Amrit Meena told PTI over phone.
Ritesh has confessed that he had an "illicit" relation with Reena, whose husband Shashikant, died 18 months ago, the officer said.
The accused came in contact with Reena while teaching some students who were her tenants, the ASP said.

The three children (besides Chhavi) were staying with Reena to pursue their studies, he added.
According to Meena, Reena with Ritesh's help used to give drug-laden drink to the four children after dinner so that they fall asleep.
On May 13 midnight, Golu woke up and saw Reena and Ritesh together, following which the duo got hold of the boy and stuffed a cloth in his mouth and bundled him in a room, he said.
Thereafter, he stabbed Ambika, Mahima and Reena to death, Meena said.
According to the officer, police were able to reach the accused with the help of the mobile phone call details of Reena.
The mobile phone details revealed Ritesh and Reena used to talk for hours with each other during night, the ASP added.
"We produced Ritesh before a local court which remanded him to 3 days police custody," the officer said, adding the knife used in the killing is yet to be recovered.
