The Iranian government has put several restrictions on the public role of women based on Islamic Sharia laws.
"When the pages of social media celebrities are identifies by FATA - Iranian Cyber Police - the admins of these pages will be referred to the judicial authorities in each provinces they live". The Washington Post reports the detainees have since been freed on bail.
Another woman wrote, "I'm dancing so that they [the authorities] see and know that they can not take away our happiness and hope by arresting teenagers and (girls like) Maedeh".
Maedeh Hojabri was seen on State TV Friday appearing to confess to her "crimes" while crying and shaking.
Hojabri was an Instagram star with tens of thousands of followers but also used multiple accounts on other social media.
"It wasn't incitement, I didn't want to encourage anyone, I didn't have an objective", she said.
"It wasn't for attracting attention", Hojabri said. In one video, she spoke about the history of parkour, an outdoor activity popular in Iran, and about women practitioners. As in Hojabri's case, Iranian TV did not show the faces of the individuals making the confessions.
The arrests at the time highlighted the divides in the country's leadership.
Iran's judiciary and security forces are dominated by hard-liners who launch periodic crackdowns on behaviour deemed un-Islamic.
With an increasing number of protests taking place across Iran amid economic woes, conservatives have adopted a more repressive approach in recent months.
Iranian woman are not allowed to dance in front of men except for close family members.
