Moghiseh, editor-in-chief of the magazine Bist-saleh ha and regular contributor to reformist news sites, was being held at Evin Prison, the BBC Persian service reported. Security forces raided his office and home at the time of his arrest, the reformist news website Kalame reported.
Moghiseh had been arrested in October 2009 and sentenced to six years in prison on undisclosed charges, the BBC Persian service reported. As they did with some other detainees, authorities freed Moghiseh on bail; he posted US$500,000 bail in March 2010. The reason for his rearrest was unclear.
A board member of the now-defunct Association of Iranian Journalists, Moghiseh was among a number of journalists and opposition politicians who investigated prison abuses in the aftermath of the contested 2009 presidential election. Moghiseh was a supporter of presidential candidate Mir-Hossein Mousavi.
