There was little about Sattar Beheshti that made him stand out in a working-class suburb south of Tehran called Robat Karim.
Like many of his peers, the 35-year-old laborer was devout and lived at home with his mother. But his life changed when he started a blog called "My Life for Iran" last year.
His entries often focused on the struggles of the working class as well as the political restrictions in Iran, sometimes mixed with personal anecdotes from Beheshti's daily life.
As months passed, the tone on the blog became sharper and more political, with unveiled criticism of the establishment and even the Supreme Leader, a red line in the Islamic Republic.
