Sources said the agency conducted the searches beginning yesterday and identified properties of a Punjab based NRI businessman presently lodged in Tihar jail on charges of drug smuggling.
Teams of the agency fanned across various locations in Noida, Gurgaon and a number of districts in Punjab and Haryana as part of the raids.
"Incriminating documents have been seized and properties worth Rs 30 crore have been identified which will later be attached as proceeds of crime of the drugs trade," official sources said.
The businessman will soon be questioned by the agency, they said.
