People living near Block 21 of the Neyveli township protested the Neyveli Lignite Corporation's move to cut unauthorised power connections in the area on Saturday. About 300 residents prevented NLC officials from disconnecting the unauthorised power connections to households. As the protest intensified, the NLC officials suspended the operation. As many as 3,500 tenements, including huts and brick structures, had come up at the place. Residents alleged that though they possessed ration cards and electors' photo identity cards, the NLC management was yet to recognise them as authorised dwellers of the area.
