The police had lodged an FIR against Mahto and five others. The Sub-Divisional Magistrate Court of Shikha Agrawal convicted Mahto and four others and acquitted one person.
Mahto has several criminal cases lodged against him in Dhanbad. On Sunday an attempt to rape case was also lodged against him.
As per the Representation of the People's Act, if an MP or MLA is convicted and given an over two-year sentence, he automatically ceases to be a legislator. But Mahto was saved as the prison term was less than two years.
