He was also the founder of "serialisation" in the Iranian press, writing stories that were published in short instalments in magazines, and which were followed by readers for years. He has serialized numerous interesting stories, each amounting to a sizable book.

Boloori was arrested and imprisoned three times during the Pahlavi regime for what he describes as "defending independent journalism."
Prior to the 1979 Islamic Revolution, he was the evening editor of the Kayhan daily and managed the incident page as well. He was summoned and interrogated a few times by the National Organization for Security and Intelligence, also known as SAVAK, for writing about the killing of a teacher in Baharestan Square in Tehran.

During the Dhofar War between local insurgents and the government in the Strait of Hormuz, Boloori traveled to the region to prepare a report. He wrote in his report that Iranian soldiers are the ones killed to retake territory, but eventually it is the British that will seize the land, and the famous Iranian singer Googoosh performs for the British.

"The British have named a military base Googoosh, and I included a photo of Googoosh performing for the British in my report," Boloori told the Iranian History program. “At that time, the government did not want the people to understand that the Iranians were being killed in the war and that they were handing territory to the British. No one should have known that the British were there. The day after the report was published, I received a call from the newspaper office telling me not to show up for a couple of days because two SAVAK agents were waiting for me by the door. I was arrested and sent to Evin Prison a few days later."

Another report by Boloori, leading to his arrest, was about a person named Zibram, a member of the Organization of Iranian People's Fedai Guerrillas. In a chase by SAVAK to arrest him, Ziberm entered a house and sent the resident woman and her child into the basement to keep them safe. He also paid the woman for a cloth he received from her to disguise himself.

Details of the story that Boloori wrote, which portrayed Ziberm's upright dealings with others, angered SAVAK. According to Boloori, prior to the story, SAVAK told people that the People's Fedai Guerrillas were "saboteurs" and "murderers," but the report showed that Ziberm had even paid for a woman's clothing. After this report, Boloori was arrested and spent about two months at Evin.

Boloori's third arrest was related to his friendship and collaboration with Khosrow Golsorkhi at Kayhan. Golsorkhri, a member of leftist parties and opposition groups, was arrested and eventually executed on charges of plotting and attempting to take hostage and to assassinate the royal family.

"Khosrow Golsorkhi was sitting next to me in the newspaper office and he was a very nice young man," says Boloori. “One day, they came and took him from Kayhan's office, and then he was tried and executed. Around the new year, we placed a photo of a clock and a rose next to it for the occasion of the new year. They arrested me for this and said that by posting a photo of a rose, I have reminded them of Golsorkhi [literally meaning 'of the red rose']."

Boloori's last detention did not last more than a month and he was released.

After the 1979 Revolution and during the "Islamic purge" of cultural and literary institutions in Iran, he was forced to resign from Kayhan and spent some time away from the press.

Between 1994 to 2001, Boloori was the editor of the incidents service for the state newspaper Iran. He later became the editor of Etemad newspaper and for a long time was in charge of the special issues of Jam-e Jam newspaper.

Mohammad Boloori was also one of the main journalists to expose the Chain Murders of Iran, which was about the murder of Iranian intellectuals and writers in the 1990s by agents of the Ministry of Intelligence. The phrase "Chain Murders," indicating that each of the mysterious deaths were linked, was first coined by him.

The novels "Lonely Poppies," "Night of the Execution," "When the Gypsies Move," "Memoirs of a Criminal Reporter," "Ten Stories for Teenagers" and "Shooting Pigeons" are works of Boloori. He also wrote the screenplay for "Night of the Sin" which was made by Davoud Molaghipoor.
