If what you stated is taken for granted, you have sent them for employment opportunities abroad (?), you are no where concerned with the employment abroad and have made this point clear to the parties ?, despite this, if the parties have undertook the risk on their own and have utilised you only as a path finder, you do not have any problem, but if know that the abroad employer is a fraudster and you have involved in this racket despite knowing this very well in advance but have not informed the parties about the risk involved, you will e deemed to have done an offence. Why did those people return from their employment, was it known to you in advance or if you are totally innocent of what has happened at abroad and you still feel that it was because of the problem of those people that they had to return t India, you can be free about it and in case of any complaint with the police, you explain your position and status clearly so that you are not held for any loss those people suffered. Before that, please see if you can help those victims who stand affected due to somebody's selfishness.
