Dhullu Mahto, a legislator of Jharkhand's ruling BJP, was on Wednesday sentenced to one-year imprisonment in a 10-year-old case related to obstructing official work, a lawyer said.
Mahto was convicted by judicial magistrate Mohammed Umar in Dhanbad district.
The BJP legislator was accused of forcefully taking away a person from the custody of the excise department and creating problems in government work in 2006.
In another case, the BJP legislator is accused of taking away an accused from the police lock-up in 2013.
The Dhanbad district court had earlier rejected the state government plea to withdraw the case.
