They were nabbed a day after the arrest of a Bangladeshi Army deserter in the same district.
Sensitive military intelligence documents and confidential papers on India's defence set-up were seized from the two men -- idenitified as Hasan Ahmed, 24, and Al Amin Mirza, 23 -- after their arrest by the Criminal Investigations Department at Basirhat bus stand, a top official told PTI in Kolkata.
"Prima facie, it is suspected that the two were on an espionage mission in India," he said. Fake Indian currency with a face value of Rs 2,500 was found in the possession of the men who did not have any valid travel documents, the official said.
On Tuesday, an army deserter and active member of Bangladesh's Jamaitul-Islami-Mujahiddin was arrested at Petropole on the border in North 24 Parganas district by the BSF.
