RANCHI, Sept. 9 -- The state unit of the Bharatiya Janata Party (BJP) staged demonstrations in six districts on Tuesday, with party workers picketing offices of deputy commissioners and superintendents of police, demanding withdrawal of cases against job aspirants during the 26-day protest against irregularities in recruitment exams. The party is also pressing for a CBI probe into the alleged irregularities in recruitment examinations. Police lodged at least six FIRs against more than 50 named and over 1,100 unnamed agitators following clashes between police and job aspirants in Ranchi, Giridih and Hazaribagh on August 23 during protest marches. State BJP president Aditya Sahu led the protest in Ranchi, while LoP Babulal Marandi headed a demonstration in Dumka. In the state capital, BJP workers took out a procession from the Zila School ground, which culminated in a demonstration in front of the district collectorate. They raised slogans against the government, demanding immediate withdrawal of cases against students during the stir against exam irregularities. "Police have lodged FIRs against students who took out marches in different districts last month. We demand withdrawal of cases against them," Sahu said....
