Six people who starred in a viral YouTube video dancing to Pharrell Williams' "Happy" were arrested in Iran. Three men and three women without hijabs were seen dancing to the hit song in an apartment on a Tehran building rooftop.

It attracted nearly 200,000 views on YouTube. For now, no explanation was given on the arrests, though some believe it is the content that runs afoul of Iranian law. The possible reason: not wearing hijabs and dancing with boys and girls together.



The original video has since been made private, but copies have been uploaded on YouTube by others.
