The Central Bureau of Investigation on Friday conducted simultaneous raids at 52 places in Jharkhand and Bihar in connection with the approximately Rs 1,000 crore land scam detected in Deoghar last year, sources in the investigating agency said.

The raids were being carried out in Patna and in Jharkhand’s Dhanbad, Dumka, Sahibganj, Latehar and Deoghar in the premises of former and current officials, who have been posted in Jharkhand’s Deoghar district registry and circle offices, besides middle men, the sources said.

The CBI took over the investigations after initial probe by the Jharkhand Vigilance Bureau.
