Actually, to be sure, both Hindus and Muslims have the surname Shah. This is one of those cases where it is difficult to tell simply by his name what religion he is. In any event, this is one of those cases where I don’t think his religion or ethnicity truly matters, unless someone is a special interest “activist” group that wants to exploit his heroics for his or her own ulterior motives.
Mitul is a Hindu name, not Muslim.
Shah is a Hindu surname and also similarly spelt, a Persian (not Muslim) title.
Mitul Shah is Hindu.
Other reports have confirmed that he is Hindu.
