The commander of Iran's navy has been questioned by the country's security services after he allowed one of his warships to be featured in a music video by a dissident rapper who has since been arrested for "promoting corrupt Western culture".
Admiral Habibullah Sayyari allowed the singer Amir Tataloo and his band to use a destroyer in the waters of the Persian Gulf to film a song that defended Iran's right to nuclear energy.
The song was released last year, but Mr Tataloo was subsequently arrested on charges of “promoting corrupt Western culture among Iranian youth”.
The admiral claimed that he did not know who the singer was and defended the decision to allow the destroyer to be used as music video set.
“I have been questioned for issuing the permission to this singer who wanted to make a short music clip in defence of our nuclear right,” he told the Jame Jam newspaper.
"The truth is that I did not know the singer’s real name and when he was referred to us he had introduced himself as Amir Hossein Maghsodloo and I thought I had never seen any productions from him before so there should be no problem.”
While the admiral has not said who has questioned him, Iran’s Revolutionary Guard’s own naval forces are responsible for intelligence and security matters of the combined forces.
The admiral said that the request to use the ship came to him through an Iranian cultural institute and that the video's producers promised to show him the footage before broadcasting it but they never did.
The final video was deeply patriotic in its message. Mr Tataloo rapped in front of a phalanx of Iranian soldiers and declared that his country had an "absolute right" to nuclear power and to defend itself against the West.
"I am an honest Iranian that is against all violence," the 29-year-old sang. "But if it's going to be by force then I will stay the path with all of my being."
According to Iranian media, Mr Tataloo made the song in the hope of getting back into the good books of Iran's morality police and eventually being allowed to perform at Milad Tower, an iconic venue in Tehran that is popular with affluent, young liberals.
Mr Tataloo was arrested in August and is awaiting charges. His music is usually not overtly political but his tattooed image, Western clothing and alternative lifestyle have led some regime hardliners to brand him "non-Iranian and immoral".
The Entekhab newspaper turned to Dr Hossien Sarajzadeh, a leading sociologist, to explain the popularity of Mr Tataloo among Iran’s young people.
“We must admit that we are now facing a new generation in our country which is completely different from the generation that made the revolution.
"They live in the cyber space and have no experience or stomach for wars or revolutions, and at the same time are facing a closed and repressive social and political system that has been born out of war and revolution,” Dr Sarajzadeh said.
