In spite of this situation, the sand island of Bri-Hasla mouza of this union has been leased to Twaki Sardar of Diadanga village of Purulia union for one year at a cost of Tk 88 lakh by the local administration.

Earlier, 35 trawlers and dredgers were used but now they are using about 15 dredgers. Local UP chairman Mozammel Hossain Pikul protested but nothing changed. I have organised a human chain with hundreds of people in the area and also lodged complaints with the OC of Kalia Police Station, Upazila Nirbahi Officer and Deputy Commissioner but no one has taken any action in this regard, said Mosharraf.
