Police said farmers and traders were among those who gathered at the collectorate this afternoon, holding black flags and raising slogans in support of their demand.
The people said they had decided on this form of protest as there was no response from the Government, despite various types of agitation to try to get them to implement the scheme.
Police quoted them as saying they would return their ration cards and Electoral identification cards if there was no assurance from the authorities concerned on implementing the scheme
Senior police officials are holding dialogue with them.
Meanwhile, five of the 10 persons on fast for the last seven days in Annur, some 35 Kms from here for the same reason, were treated for fatigue, police said.
Protestors claimed all political parties had expressed support to their agitation.
