Protests intensified on Friday over the demand for cancellation of the recent Bihar PSC exam, as agitators disrupted rail and vehicular movement in Patna.

A day ahead of fresh tests for a select group of candidates, Independent MP Pappu Yadav led his supporters in blocking rail and road traffic in several areas of Patna as well as other parts of the state, including Araria, Purnea and Muzaffarpur, officials said.
