Bharatiya Janata Party (BJP) legislator Vishnu Kumar Raju declared Special Investigation Team (SIT) to probe Vizag land scam is a waste of time, because it's jurisdiction is limited. It will deal only with tampering of revenue records, which has already been done in a way by the collector. Unless the scope of SIT is increased, there is no need for it at all, he said. He is about to write to Chandrababu, on this, he said. There is a demand by Opposition parties for Central Bureau of Investigation (CBI) probe in to the incident.
