Idukki: One-year-old twin boys died after they allegedly put an unidentified liquid found on the kitchen floor into their mouths at their home in Irumbupalam near Adimali on Friday evening.

The deceased have been identified as Ihan and Rihan, sons of Afsal and Sandra of Valiyakattil House at Ozhuvathadam in Mannamkandam, Adimali.

The incident occurred around 7.30 pm on Friday. Their parents and neighbours rushed them to hospital for treatment.

However, Ihan died at Adimali Taluk Hospital at around 9 pm while undergoing treatment. Rihan was shifted to Morning Star Medical Centre in Adimali, where he died around 10.30 pm.

Afsal reportedly told police that he suspected the children had accidentally consumed paint thinner kept at the house. However, police have not yet confirmed the nature of the substance and are also examining whether it could have been another chemical liquid kept at the premises for agricultural purposes.

The house has been cordoned off to preserve evidence, and a detailed forensic examination is pending. The bodies have been kept at the Government Taluk Hospital in Adimali and will be handed over to the family after postmortems.

Adimali police have registered a case under Section 194 of the Bharatiya Nagarik Suraksha Sanhita (BNSS) in connection with the unnatural deaths and launched an investigation.
