Tehran - Iranian police have arrested a woman journalist who covered parliament for pro-reform media on orders from the conservative-controlled judiciary, the pro-reform Sharq newspaper reported on Thursday.
"Saba Azarpeyk was arrested yesterday [Wednesday] morning at her home," the daily said, adding that the grounds for her arrest were not immediately clear.
She reported on parliament for several pro-reform outlets, including the prominent Etemad newspaper.
She was among 18 journalists for reformist media who were arrested in January 2013 for allegedly working for the Farsi-language services of foreign media deemed hostile by the authorities.
President Hassan Rouhani, a self-declared moderate, has promised greater tolerance on social, cultural and media issues - a pledge that helped him defeat conservatives in last June's election.
But the fledgling opening has been opposed by traditionalists and ultra-conservatives, who hold sway over several key institutions.
Conservative newspapers as well as reformist ones have faced temporary bans from the conservative-controlled judiciary since Rouhani took office but three pro-reform titles are under continuing bans.
