On 18 April 2010, it was reported that he was sentenced three-and-a-half years in prison. His protest was called "unexpected" as he was "a prominent Iranian conservative respected by supporters" of the Islamic regime, and "explicitly targeting" the Supreme Leader for criticism in his letter. The letter read in part,
"As commander in chief of the armed forces, you didn't treat people well after the election. Your agents opened fire, killed the people, beat them and destroyed and burnt their property. Your role in this can't be ignored,... Your apology can cool down the wrath of the people."
A year earlier he had "aroused a wave of protest and criticism" with an article on his blog calling for Iran’s leading clerics to avoid getting involved in governmental affairs, after several such clerics called for the dismissal of President Mahmoud Ahmadinejad's vice president, Esfandiar Rahim Mashaei.
Hunger strike
On 11 December 2010, Nourizad started a hunger strike to protest a lack of attention from Iranian authorities to his complaints of alleged mistreatment by interrogators at the Evin prison. On 16 December authorities detained his family members after they showed up outside the prison to inquire about his failing health.
On July 15, 2013, Nourizad kissed the feet of a 4-year-old Bahá'í boy whose parents had been arrested for participation in the Bahá'í Institute for Higher Education, saying: "…why shouldn't I kiss your feet as a representative of the office of and the Shi'ite sources of emulation?" and published the event on his blog. The boy's father responded in a letter from prison dated July 18 saying in part: "Mr. Nourizad! Standing before Artin, you knelt and kissed his feet. I found this to be an utmost expression of love and respect, not to Artin but to the pure human spirit. At the same time, I wish that no person be forced to kneel before another person out of shame. …. Mr. Nourizad! You asked Artin to slap you and to spit on you. I heard this request as your attempt to ease his pain, and the utmost sign of your honesty and your acceptance of responsibility. At the same time, I wish that no human body should have to be exposed to such a thing, as the body houses the human spirit and the human spirit is a display of the Divine one." In September 2013, Nourizad filmed Mohammad Maleki, former Rector of the University of Tehran, publicly apologizing in a similar way for his part in turning away Bahá'í students from Iranian universities.
Voice from prison
On 29 April 2020 a voice file attributed to Mohammad Nourizad was published on Shirin Ebadi's official Telegram channel, in which Mohammad Nourizad, from Vakil-Abad prison in Mashhad, announced:
“… as to protest against the pressure on my family, I decided to commit voluntary suicide and its news will spread in ten, five, six days. I didn't voice but veracity. I am here for telling the truth; then the liars and the thieves and the murderers are out. I wish, one day, get rid of Mullah and the irresponsibles and the non-transparents”.
Curiosity
It is not possible to add Shirin Ebadi's official Telegram channel as "cite" on this Wikipage in Persian language, as it warns that Telegram is in the blacklist of Wikipedia.
