According to statistics by the Baha'ism organization, 300,000 Baha'is are living in Iran. Of course, this statistics are unreal and are exaggerated; but a few Baha'is have been arrested and punished. It is interesting to be noted that all human right media have stated that these Baha'is have been arrested merely due to being Baha'i.
Why just 100 Baha'is have been imprisoned in Iran?!!!
Consequently, no Baha'i has been merely arrested and punished due to being a Baha'i; but they may proselytize Baha'ism, hold illegal meetings and ceremonies, cooperate with the obstinate media against the national security, presence in riots and etc. to be arrested and punished.
