Members of the DMDK and PMK staged a protest against illegal mining of sand near Vaippar on Wednesday.
They alleged that sand was being lifted to the depth of up to 30 ft after getting permission for lifting savadu soil of up to 3 ft depth at Keezhnattukurichi near Ettayapuram. The sand was being taken using 400 tipper lorries, they added.
They also raised slogans demanding compensation be paid to the government.
Despite repeated complaints to authorities, the politicians said that no action was being taken. DMDK north district secretary Azhagarsamy, district deputy secretary Malairaj, PMK State deputy secretary Ramachandran, district secretaries Vinoth and Chinnadurai, Kovilpatti town secretary Kalidas and other party functionaries participated in the protest.
