"Heerkibai, Sarpanch of Padalghati village, had called the victim, identified as Gopal Masudia, to her village on some pretext and later killed him in connivance with her husband Ram Singh and son Kaigu," DSP Rachna Bhadouria told reporters today.
The incident had taken place around one-and-a-half months back.
Heerkibai was apprehended yesterday and confessed to her role in the crime, she said, adding the search is on to trace Ram Singh and Kaigu.
According to police, Heerkibai was having an illicit affair with the victim. "On the day of the crime she had called Gopal to her village where her husband and her son attacked him with a sword resulting in his death," Bhadouria said.
Gopal's body was found dumped at a secluded place under Kalyanpura police station limits.
