Prosecutors say the two had classified information regarding security operations in Rakhine state, from where hundreds of thousands of Rohingya Muslims fled during an army-led crackdown the United Nations has dubbed 'ethnic cleansing'.
A Bangladesh border guard official said that a 15-year-old Rohingya refugee was shot in the elbow on November 4 while grazing cows after multiple rounds were fired from a security post across the demarcation line.
Before their deportation, the UN had voiced concern that returning the men ignored the danger they faced in Myanmar, where for decades the Rohingya have been targeted in violent pogroms by security forces.
"The Indian Government has an obligation to refer Rohingyas under their custody to the UN refugee agency so their protection needs can be assessed and proper information provided to them about their rights," the UN expert added.
"We are aware that a large number of Rohingyas are assembled there in Bangladesh and from time-to-time some small groups did try to enter India, but I am very happy to say that we did not let them succeed," the DG said.
