In another major step towards demolishing the terrorist-gangster-drug smuggler nexus in the country, the National Investigation Agency (NIA) on Saturday attached four properties owned by members of dreaded gangster Lawrence Bishnoi's organised terror-crime syndicate. Of these properties, three were immovable and one was movable. The properties were attached in a coordinated swoop by the NIA teams in Haryana, Punjab and Uttar Pradesh under the provisions of the Unlawful Activities (Prevention) Act, 1967.
