Cheni, April 2: It was a day of protests in Tamil du on Monday against the Central government’s failure to set up a Cauvery Magement Board (CMB) despite a Supreme Court order. Activists of the DMK and other organisations staged noisy demonstrations protests here and in other parts of the state. DMK members protested at several places in the city including the arterial An Salai stretch in Saidapet, disrupting traffic. In Coimbatore, around 500 km from here, DMK members stopped a train by squatting on train tracks. The party and its allies have called for a shutdown on April 5 over the Cauvery issue. Members of some fringe organisations picketed post offices and Central government offices in the state. In Manrgudi, students protested outside their colleges.
