The two were held when they were about to leave for Kolkata with the contraband, Superintendent of Police Manoj Kaushik said.
Rs 61,100 in cash, one cell phone and two SIM cards were also recovered from them.
"The two were identified as Ziaul Sheikh and Samputi Sheikh who claim they belong to Murshidabad district in West Bengal. But they could not produce any documents. Police, however, have confirmed information that they are Bangladeshi nationals," Kaushik said.
