A 35-year-old zoo attendant was attacked and killed on Tuesday by a Royal Bengal tigress in Itanagarโ€™s Biological Park in Arunachal Pradesh.

The deceased has been identified as Poulash Karmakar, a native of Dhekiajuli in central Assamโ€™s Sonitpur district.

Zoo curator Raya Flago said the incident occurred at 2.30 pm on Tuesday when the zoo attendant entered the tigressโ€™s cage to clean the water pond.

โ€œThere are three gates that lead to the cage and all of them were left open. We are assuming that this led to the tigress attacking the zoo attendant,โ€ Flago said while adding that a police investigation has been launched in the case.

A case under unnatural death has been lodged at the Itanagar police station and the body of the deceased has been sent for post-mortem at the R K Mission Hospital.

Police said the body of the deceased would be handed over to his family members after the post-mortem examination.
