Continuing its controversial anti-encroachment drive in the national capital, the BJP-governed civic body today rolled into Madanpur Khadar in South East Delhi and demolished several structures it deemed as illegal construction. Amid loud protests by local residents who claimed they were given no prior intimation, bulldozers could be seen trying to demolish a six-storey building in the area. Several workers armed with hammers could also be seen pounding at the building from inside.
