During sustained interrogation, Mani Pratap Kaushal confessed he had strangulated his sister Kanchan with an electric wire as he doubted her character, SSP Rakesh Aggarwal told mediapersons in Hoshiarpur today.

Mani, a resident of village Kitna, told police he had killed his sister, aged 16, for having an affair which had incensed the family, Aggarwal said.

After strangulating her, the youth said he wrapped her body in a bedsheet and threw it in a canal, the SSP said.

Earlier, Surinder Singh, the father of the girl, had filed a report with Mahilpur police station that his daughter was missing since June 29.

After serving dinner to the family, she had left the house without informing anyone, the father said in the complaint, according to the SSP.

A few days later, a body was fished out from a canal in Kapurthala district and police called Surinder Singh’s family to identify the body.

Mani went to the Rawalpindi police station but failed to identify the body.

However, during investigations Mani emerged as the main suspect and was arrested, the SSP said.

During interrogation, Mani revealed he had laced the dinner with intoxicants and went outside the house.

After consuming the dinner, the family members became unconscious and at around 1am, he strangulated Kanchan with an electric wire, he told his interrogators.

Later, he wrapped her body in a bedsheet and threw it in a canal near the village, the SSP said.
