Ever since, Nagpal took charge as SDM, she has been sending out special squads, to stop sand dredging and loading onto trucks. She has arrested 15 people and imposed fines of several crores on those caught. Hundred of trolley and dumpers have been confiscated. The sand mafia was obviously rattled. In fact the entire construction industry was in a state of shock. And this construction industry is one of the biggest in the country – Sports City, Greater NOIDA Expressway, 82 colleges, four universities and apartment blocs upon apartment blocs. This requires sand. But license for mining along twenty miles of the river is granted only to one person. This dummy “miner” is the cover for hundreds of crores worth of sand.
