One more rhinoceros was found dead on Saturday in the flood waters at Assam's Kaziranga National Park.
While a total of six rhinos have died in the past four days in poaching and flood-related incidents, the toll since the third wave of floods began on September 21 has gone up to 10.
Body of the female rhino, with its horn intact, was found floating in the flood waters at Gorakati under Bagori Range of the park on Saturday.
The horn from the body of the rhino was handed over to the forest department.
The carcass of the pachyderm was recovered during routine patrolling in the park, which has most of its 430 sq km area under flood waters.
Meanwhile, a three-member central investigation team has arrived here to probe the sudden spurt in the poaching of rhinos in Kaziranga, a World Heritage Site.
Assam Chief Minister Tarun Gogoi is confident that the CBI inquiry recommended by his government into rhino killings will help in nabbing the culprits.
The killing of rhinos had earlier sparked off protests in the state, with several organisations including the All Assam Students' Union, the Assam Jatiyatabadi Yuba Chatra Parishad and Krishak Mukti Sangram Parishad blocking the NH-37, which runs through the Park.
United Liberation Front of Asom's Paresh Barua led anti-talk faction has also condemned the killing of rhinos and accused the government of failing to save Assam's heritage.
Prominent conservation group Aaranyak has alleged that the failure of the intelligence network and lack of coordination among concerned authorities, besides "poor" commitment on the part of officials is the main cause behind poaching incidents in the park.
