Kolkata: About 17 kg of elephant tusks, valued at Rs 1.69 crore, was recovered by the Directorate of Revenue Intelligence (DRI) on the outskirts of Siliguri in north Bengal on Wednesday.

One person was arrested, a DRI official said.

The elephant tusks, cut into four pieces, were being clandestinely transported in a vehicle that was loaded with a consignment of black tea.

"Driver of the vehicle was arrested and consequently, the elephant tusks valued at about Rs. 1.69 crore in the international market have been seized under the provisions of the Customs Act, 1962 read with the Wildlife Protection Act, 1972," the official said.

On interrogation, the driver of the impugned vehicle confessed that the elephant tusks were handed over to him in Baihata Chariali by an unknown person from Guwahati for transporting these to Kolkata.

Preliminary investigation revealed that the tusks were extracted from poached elephants in the forested areas of Assam and were being carried to the eastern metropolis for ultimate export to South East Asian countries via Bangladesh, the official said.

According to the agency, Indian (Asian) Elephant (Elephas maximus) is listed in Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora and also in the Wildlife Protection Act, 1972.

DRI has detected a series of cases involving trafficking of elephant tusks. In four such cases in the past, a total of 38.604 kg of elephant tusks have been seized by the agency last year. Eight persons have been arrested in these cases.
