Seeping sewage into the basement of their residential complex has prompted about 100 families of Sharda and Vivekananda, two blocks of Gadadhar Apartments, at Adarshnagar in Sonari to knock on the doors of BJP leader Sarayu Roy. The residents approached the former MLA after the Jamshedpur Notified Area Committee (JNAC), which looks after the upkeep and sanitation of the area, turned a deaf ear to their pleas to take some measures. Roy today made an on-the-spot assessment and promised to take up the matter with East Singhbhum deputy commissioner R.K. Agarwal.
