“The Foreign Office takes reports about detentions of German nationals very seriously. Our embassy in Tehran is investigating the report intensely and has confronted the Iranian side at a high level with the reports,” the source said.
No further details were immediately available on the identity of the detainee or the circumstances of their arrest.
On Saturday, Iranian Finland-based journalist Kambiz Ghafouri reported the alleged arrest of a male German citizen in Iran, saying he is currently in quarantine at Tehran's notorious Evin Prison.
In January, the European Parliament adopted a motion for a resolution condemning Iran’s detention of European Union citizens, labelling the practice as “hostage diplomacy.”
The resolution called for the immediate release of detained EU nationals and for a stronger coordinated diplomatic efforts by EU member states.
In its resolution, the European Parliament “strongly condemns Iran’s use of hostage diplomacy” and calls for the immediate and safe release of all EU citizens held in the country, including Olivier Grondeau, Cécile Kohler, Jacques Paris, and Ahmadreza Djalali.
