In another incident, an Indian father has been accused of mercilessly throwing his two-month-old infant into a lake, claiming that the baby did not resemble anyone in his family and speculating that child was his wife's offspring with another man, Latin Times reported.

The incident happened at Kalyandurg in the Anantapur district of Andhra Pradesh, India on Oct. 21. The accused, identified as Mallikarjuna, a former insurance agent, reportedly took his wife Chittemma and their two-month-old daughter to a hospital for a medical check-up on Oct. 21.

However, when the baby started crying while they were waiting for the doctor's appointment, Mallikarjuna took off with the infant, telling his wife that he was taking her outdoors to pacify her.
