The All Assam Students' Union (AASU) will stage a Statewide protest on May 3 in protest against the spurt in rhino poaching. Reiterating that a CBI probe be initiated to get to the roots of the rhino poaching, the AASU said that Forest Minister Rockybul Hussain had proved to be totally incompetent in checking rhino deaths and Chief Minister Tarun Gogoi was turning a blind eye to the developments. "Forests and wildlife are facing a never-before threat, with the timber mafia clearing pristine forests and poachers decimating the endangered rhino in an unprecedented manner. We will not stop until the Government accords top priority to the menace,' the AASU said. It may be recalled that as many as five rhinos have been killed by poachers in Kaziranga and Orang national parks in the past couple of weeks.
