New Delhi, Aug. 7 -- The National Investigation Agency (NIA) on Thursday arrested two Haryana residents in the case of human trafficking of illegal immigrants to the US via the infamous 'Dunki' route.

Ravi Kumar and Gopal Singh were arrested during extensive searches at four locations in Haryana and Punjab in the case, said the NIA.

"While two locations were searched in the Karnal district of Haryana, NIA teams converged on one location each in Yamuna Nagar (Haryana) and Gurdaspur (Punjab) this morning," the anti-terror agency said in a statement.

The digital devices and other material seized during the searches are being examined for further evidence about the criminal conspiracy linked to the immigration racket.
