Senior Trinamul Congress leader Anubrata Mondal and 13 others were acquitted on Friday in a 2010 case of violence at Mangalkot in Birbhum district by an MP/MLA court here on Friday.
Mondal and the 13 others were accused in the case of political violence in March, 2010, in which some people were injured.
The judge of the MP/MLA court acquitted Mondal and the others for want of evidence.
