A suspect in a security-related case has suddenly died mid-trial in a Revolutionary Court in Tehran.

Fars news agency, with close ties to the Islamic Revolutionary Guard Corps, claimed the suspect had come to the court from his home and "collapsed while defending himself in the courtroom".

Preliminary assessments by emergency personnel suggest that the cause of death was attributed to cardiac arrest but the suspect's body has been transferred to forensic medical authorities for more comprehensive examinations and specialized tests.

Reza Khandan, the husband of Nasrin Sotoudeh, a well-known Iranian lawyer and human rights activist, shared a message on the X media platform on Saturday (November 4). He identified the man as Saeed Khademi.

Khandan wrote that the suspect was born in 1962 and had been summoned for trial on charges including "insulting sanctities" at Branch 29 of the Revolutionary Court, and collapsed in the courtroom. The charges are commonly issued by the regime in its sham trials, not least in tenuous cases relating to security charges.

"His sister has mentioned that he had been under immense stress related to the trial for several days", Khandan wrote.
