Vahid Razavi, a member of Vadi’s family, told Iran International that the researcher was detained about 18 months ago following a dispute at work and was later accused of spying for Israel.
“Rouzbeh was tortured intensely, to the point that bones in his leg and two ribs were broken, and then his mother was arrested and jailed,” Razavi said. Interrogators, he added, photographed her in custody and showed the images to Vadi “to extract a forced confession.”
“They had told Rouzbeh that if he did not confess to espionage and agree to appear in a televised interview, they would torture his mother.”
Vadi, who held a doctorate in reactor engineering, had co‑authored a 2011 research paper with senior Iranian nuclear experts later killed during the June conflict with Israel, according to his Google Scholar profile.
The judiciary said he was convicted of transferring classified information about one of the scientists killed in those attacks to Mossad.
According to Razavi, interrogators warned Vadi that unless he admitted to espionage and appeared in a televised confession, “they would torture his mother.” He said Vadi accepted what he called a fabricated charge under those conditions.
Televised confession questioned
Vadi, a member of the Nuclear Science and Technology Research Institute affiliated with the Atomic Energy Organization, was executed on August 6. The judiciary said at the time he had been “recruited via cyberspace by Mossad.”
The confession, Razavi said, broadcast on state television was the sole basis for the conviction. He said authorities “moved quickly” after the 12-day conflict in June and carried out the execution without notifying the family.
Razavi also questioned state media remarks that Vadi received a black bag stuffed with cash. “In an era of digital transactions, why would a highly educated scientist accept cash in a bag?” he said.
Vadi, Razavi said, was portrayed as having copied sensitive files onto a hard drive and handed them over in a public park restroom. Such accounts, he argued, were “nonsensical” given the availability of secure digital platforms such as Signal or Telegram.
Rights organizations have long raised concerns about forced confessions obtained under torture in Iran’s judicial system.
Razavi described Vadi as intelligent, devoted to his family and focused on work, noting that he lived with his mother and had modest means. He said Vadi had no political involvement and was committed to supporting peaceful nuclear research.
Following the June war, Iranian courts have arrested, tried and executed several people on espionage charges involving Israel. In one recent case, political prisoner Javad Naeimi was executed on October 18 in Qom. These executions have drawn criticism from international human rights groups and UN rapporteurs.
