Reformist Iranian journalist and former student activist Saeed Razavi Faqih has been reportedly arrested upon returning to Tehran from Paris where he was residing.
Friends of Razavi Faqih have said that he has been missing for about a week when he traveled back to Iran.
Reports say he was detained at the airport and transferred to jail. The reason for his arrest is not clear.
It comes amid a new wave of crackdown on journalists, bloggers, and activists ahead of the March parliamentary elections.
