A limited liability company linked to investment fund D.E. Shaw Group recently paid $3 million for 352.6 acres of mostly agricultural land in East Granby. River Bend Holdings LLC sold four properties in the town’s south end to Broadleaf Solar LLC in a deal recorded Dec. 30, according to town records. Both limited liability companies track back to larger entities. River Bend is controlled by Indus Realty Trust, an industrial and warehouse landlord that got its start in Connecticut’s tobacco trade. The company changed its name from Griffin Industrial Realty last year.
