Kasra Nouri was arrested for the first time in 2011, when security forces raided his home in Shiraz. He was subsequently detained for 45 days after which he was released on bail for the amount of 50 million tomans. However, shortly after he was released on bail, he was arrested once again on March 15, 2012, for conducting an interview with Radio Farda.

At the time of his arrest he was aged just 21 years old. On April 24, 2013, after having spent 15 months in temporary detention, Branch 3 of the Islamic Revolutionary Courts sentenced Nouri to four years and four months imprisonment. He was subsequently transferred to Adel Abad Prison in Shiraz in order to serve his prison sentence. Kasra Nouri was released on October 30, 2015.

Kasra Nouri was arrested along with four other Sufi Dervish students at the Dey General Hospital three days after the start of the widespread protests of December 2017. A number of other Sufi Dervish students staged a sit-in protest in front of Evin Prison to protest their arrest. Eventually, on January 9, 2018, after ten days of detention and hunger strikes, Kasra Nouri was released from the Rajai Shahr Prison in Karaj. After his release, Nouri joined the other Sufi Dervish students in their sit-in protests outside of Evin Prison.

Kasra Nouri’s most recent and current arrest was related to the events of the Haftom-e Golestan Protests, also known as the  2018 Dervish Protests, during which Kasra and a number of other Sufi Dervishes were assaulted, beaten and arrested. 

Nouri served a sentence at Evin Prison, where he has gone on repeated hunger strikes to protest against prison conditions for dervishes. The Prosecutor General of Tehran also arrested Nouri’s mother and his two brothers to intimidate and put pressure on Nouri.

On August 12, 2018, Kasra Nouri and his other family members were sentenced to a total of 25 years imprisonment. Kasra Nouri alone was sentenced to 12 years imprisonment, 74 lashes of the whip, two years compulsory exile in Salas-e Babajani County, a two-year travel ban, a two-year ban on the membership of any political or social groups, parties or associations and a two-year ban on any media activity. Amir Nouri, Kasra’s brother, was sentenced to six years imprisonment, Porya Nouri, Kasra’s other brother, was sentenced to two years imprisonment and Shokoofeh Yadollahi, Kasra’s mother, was sentenced to five years imprisonment.

The three members of Kasra’s family have since been released from prison. However, no form of pardon or amnesty has been granted in Kasra Nouri’s case and he is still currently in prison.

Kasra Nouri has been imprisoned in Tehran's Fashafoyeh Prison for one year and ten months, he was also imprisoned in the Adel Abad Prison of Shiraz for about a year, and he has been imprisoned in Evin Prison in Tehran since February 2021. On a number of different occasions Kasra Nouri has been persecuted, harassed and beaten in prison by prison officials.
