The Iranian government has previously detained women for dancing in public.
But before her detention, Hojabri, who is in her late teens, reportedly posted dozens of clips of herself dancing to Iranian pop music and Western tunes like DJ Snake's "Let me love you" and Sia's "Cheap Thrills". Her videos attracted tens of thousands of followers.
Social media users have shared their own videos and messages of support for Miss Hojabri using the hashtag #dancing_isn't_a_crime.
State TV broadcast a video in which Maedeh Hojabri, 18, acknowledged breaking moral norms while insisting that was not her intention. I did not want to encourage others to do the same. In numerous videos, she did not wear a hijab, which is mandatory for women to wear in public in the country.
Iranians on social media mocked clerical rulers on Monday after the hard-line judiciary arrested a teenage girl for posting on Instagram videos of herself dancing in her room. "I did not work with a network", a crying Hojabri told TV on Friday.
There has been widespread outcry over the arrest of Hojabri and the other detainees among Iranians in Iran and overseas, by artists, journalists, activists, politicians and thousands of ordinary citizens on social media.
Iranian police have also arrested other popular Instagram users as part of what appears to be a broader crackdown against the social media platform. But more importantly, she is a fearless great warrior against the barbaric regime who took a nation in hostage.
Iranian authorities have previously cracked down on dancing.
In September 2014, seven young people were sentenced to prison time and flogging, sentences that were later reduced upon appeal, for producing a video of themselves dancing to Pharrell Williams' "Happy" at different locations in Tehran.
In August past year, six women were arrested for dancing Zumba, a modern and popular dance style.
