Iranian singer Parastoo Ahmadi was arrested on Saturday after performing a YouTube concert without wearing a hijab, her lawyer told local media.
"As of noon today, we did not know about the situation of my client, Parastoo Ahmadi," her lawyer Milad Panahipour said.
Local media also reported that two of Ahmadi's musicians - Ehsan Birghidar and Sohail Faqih Nasiri - were arrested.
The news comes after Ahmadi performed the concert on Wednesday in defiance of Iran's strict morality laws for women.
Alongside the mandatory hijab law, women are also not free to sing publicly in Iran.
Ahmadi performed without an audience but broadcast the concert live on her YouTube channel.
Iranian authorities announced that Ahmadi would be tried immediately after the concert was broadcast. »
