Iran’s judiciary on Sunday confirmed the brief detention of a member of Iran‘s negotiation team with world powers on suspicion of “infiltration,” the official IRNA news agency reported.

On Wednesday, hard-line news outlets said authorities detained a dual Iranian-Canadian national, Abdolrasoul Dorri Esfahani, a member of the Ontario Institute of Chartered Accountants in Canada.

The Sunday report by IRNA quoted judiciary spokesman, Gholamhosein Mohseni Ejehi, as saying, “The report is correct. He was released based on bail. Yet, his charge is not proved.”

He neither elaborated on the case nor identified the suspect by name. However IRNA called the suspect, an “infiltrating element.”
