Your own leeches from either Assam or WB. Why they claim to be 'Bangladeshi' is anyone's guess.
By the way - you will find 60 illegal Indians on any given street corner at any time in Dhaka - and these people are a lot better paid, working in apparel industry (not street sweepers or security guards). The difference between you and us is that we realize these people are trying to feed their families, that is all.
Even if these people were Bangladeshi (for argument's sake) what danger do they pose to India or Indians?? Destitute migrant workers will go anywhere to make a better living, yes even India.

Tell your Shakha-chalak to stay off the Cowka-Cola. He's been swilling a lot of it, seeing things and giving you all the propaganda.
