New Delhi, May 25 (TIWN): Iranian authorities have arrested around 30 people at a private yoga class in the northeastern city of Gorgan for 'inappropriate outfits'. The officials were tipped off by an Instagram advertisement.

The incident comes after social media accounts of three prominent Iranian street musicians were apparently seized by authorities in the country for publishing "criminal content". According to Tasnim news agency, a local justice department official said that both men and women who were practising yoga in a private home were arrested.
