A German businessman has been arrested after allegedly setting up an unsuccessful deal to sell to Iran material that could have been used for building missiles, German prosecutors said Monday. The federal prosecutors said the 62-year-old, identified only as Hans-Josef H., was arrested on Friday. They said he was a manager at an unidentified company in the western German state of Rhineland-Palatinate. The man is suspected of violating German export laws, the prosecutors said in a statement. Between May 2007 and this month, the suspect defied international sanctions by organizing a circuitous deal to deliver goods to a blacklisted recipient in Iran, the prosecutors alleged, without identifying the recipient.
