Dozens of Mahasabha activists along with Sonari Gram Sabha assembled at the Sakchi roundabout and set on fire the Das' effigy.
The East Singhbhum unit president of Mahasabha, Krishna Hansda said the appointment of Das was in violation of sections 13(iii)(a), clause 19(5 and 6), which bars an outsider to seek employment or settle in a Schedule area.
Majority blocks of Jharkhand comprise of schedule areas, he claimed adding the adivasi community believed Das' election as MLA and Chief Minister was "illegal" and "unacceptable".
"How can an outsider frame policies in the interest of the tribals?" he asked expressing apprehension that the policies to be framed by outsiders would be a non starter for development.
