The construction work of the retaining boulder wall of Diphu River by Diphu Town Committee (DTC), for which Rs 8 crore has been sanctioned, is going on. There were news reports that contractor Chiranjit Agarwal had siphoned off the money without completing the work. This was, however, refuted during a press meet by Town and Country Planning executive engineer, Nipu Charan Dutta, Diphu Town Committee engineer Pradip Rongpi and Town and Country Planning deputy director Rumen Ronghang.
