Bangladesh Chhatra Union (BCU), a left-leaning student organisation, yesterday demanded expulsion of Indian High Commissioner Pinak Ranjan Chakravarty for his "audacious comment" on local experts who are raising voice against Tipaimukh Dam project.
At a rally on the Dhaka University campus, BCU leaders said India has taken an initiative to build the dam on Borak river without discussing the issue with the Bangladesh government.
Once the dam is built, it will have disastrous impacts on the economy and the environment of Bangladesh, they added.
The BCU leaders also stressed the need to forge a mass movement across the country against the Tipaimukh dam.
The navigability of two rivers -- Surma and Kushiara -- would seriously be hampered seriously if the dam is constructed, they said.
They also called on the government to clarify its stance on the Tipaimukh dam.
BCU general secretary Manabendra Dev, Khan Asaduzzaman Masum, Ferdous Ahmed Ujjal, Mahamudur Rahman Birol and Abu Toab Apu spoke at the rally.
Earlier, the student organisation took out a protest procession.
