How to find the whereabouts of the wife and returning her home

My wife came to Dubai and has abandoned the family (Husband and 2 kids - 9yrs and 7 yrs). We don't know her whereabouts and she has blocked us from every contact.

She is complaining everywhere that I am abusive and don't take care of her but the fact is she has had illicit affair in India before coming to the UAE and wanted to get married to that other person as well.

Is there any way I can do something to get her back to family legally?
