A British-Iranian university professor on security charges, justice officials in Tehran have confirmed.
Abbas Edalat, a computer scientist and mathematician at Imperial College London, was reportedly arrested earlier this month by the Revolutionary Guard, which has detained several dual-nationals in recent years.
Iran’s official IRNA news agency on Sunday quoted judiciary spokesman Gholamhossein Mohseni Ejehi as saying Mr Edalat had been detained on “security charges”, without elaborating.
It was the first official confirmation of his arrest.
On Thursday, the semi-official Fars news agency said Mr Edalat was one of several people arrested by the Guard over accusations of being part of a “network affiliated with Britain”.
Mr Edalat had actively campaigned against Western military action targeting Iran.
