Six young men and women in Iran have been released by the country's police, after they were arrested for appearing in a parody video of Pharrell William's hit song Happy.
The video's director, Sassan Soleimani, was still being detained, according to the New York-based International Campaign for Human Rights in Iran. The organisation also quoted a source close to the family of one of those arrested as saying the group had been told they would be prosecuted.
Since it was uploaded to YouTube on May 19, the footage has garnered over 300,000 views. It shows three women, not wearing headscarves as required by the country's law, and three men, lip syncing to the song while they dance on a roof and inside a home in the capital Tehran.
The video, which imitates thousands of similar clips by other Pharrell Williams fans, was accompanied by the description: "We have made this video as Pharrell Williams' fans in 8 hours, with iPhone 5S. Happy was an excuse to be happy. We enjoyed every second of making it. Hope it puts a smile on your face."
