A 24-year-old woman and her teenage lover allegedly killed the former's 10-year-old son in India to hide their illicit relationship.

The incident took place in the western state of Rajasthan. The woman was arrested, and the 14-year-old boy was detained in connection to the death of the child, the police said Monday, the Print reported, citing Press Trust of India.

The 10-year-old child had reportedly seen his mother and her nephew in an intimate position last week. Fearing the boy will disclose the incident to other family members, the woman and the 14-year-old murdered the 10-year-old child.

The police said the duo allegedly dumped the child's body in a water tank. The child's corpse was recovered from the well on Feb. 10, a day after he was killed.

During investigation, the police questioned the child’s mother, who was identified as Meena, the wife of Taga Nath, and her 14-year-old nephew.

The nephew told the police he and his aunt were in an illicit relationship for more than a year.

“They were in a relationship for more than a year. The 14-year-old took Harish to a school and murdered him by covering his face in order to suffocate him. At night, he threw the body into the water tank,” senior police officer Priyanka Kumawat told the Times of India.

The 14-year-old involved in the incident has not been identified.

Last year, a 21-year-old woman was arrested along with her stepfather-turned-lover for plotting her mother’s murder. The incident took place in December in the southern state of Karnataka. The victim, Archana Reddy, 42, was hacked to death by a few men. Her minor son was also with her when the incident took place. The police said Yuvika Reddy, Archana's daughter from her first husband, had an illicit relationship with her stepfather, 33-year-old Naveen Authorities added Yuvika and Naveen decided to murder Archana after she decided to not give her daughter any property. She took the decision after learning about her daughter's affair with Naveen, who then reportedly sought the help of his friends to kill the woman.
