Iranian authorities have arrested another labour and human rights activist in Tehran.
Security forces arrested Ali Akhavan yesterday at his home, and his whereabouts have not been announced yet, the Human Rights Reporters Committee reports.
Akhavan was arrested once before in June of 2010 and released on bail after 25 days. He was later sentenced to three years in jail, which was reduced to one and a half years in the appellate court.
Recent weeks have brought signs of a country-wide crackdown on labour activists.
Mohammad jarahi, Shahrokh Zamani, Sheys Amani, Sharif Saedpanah and Mozafar Salehnia are among the other labour activists arrested in recent months.
