Iran’s regime confirms arrest of 18-year-old Lennart Montrelos amid growing tensions over imprisoned Europeans, including French citizens Cecile Kohler and Jacques Paris.
The Iranian regime has confirmed the detention of Lennart Montrelos, an 18-year-old Franco-German cyclist who went missing in Iran on June 16, 2025. In an interview published Thursday by Le Monde, Iranian regime Foreign Minister Abbas Araghchi stated that Montrelos is in custody for “committing a crime” and that the French embassy had been “officially notified.”
Montrelos, a recent high school graduate from Besançon, France, had embarked on an ambitious solo bicycle journey intended to span 35 countries over 400 days and 20,000 kilometers. His last public trace was an Instagram selfie posted on June 15 in southeastern Iran, captioned with a mix of irony and wonder: “I’m in the most dangerous country in the world – with the nicest tea.” Since then, there has been total radio silence, leaving his family, friends, and followers increasingly anxious.
The French Foreign Ministry, which has previously accused Iran’s regime of taking foreign nationals hostage as political leverage, expressed deep concern over Montrelos’ unknown status before Araghchi’s confirmation. A diplomatic source told AFP that France is in contact with both Iranian regime authorities and Montrelos’ family regarding the case.
A Pattern of Hostage Diplomacy
Montrelos’ detention comes amid growing international criticism of Tehran’s so-called “hostage diplomacy”—the arrest of foreign citizens, often on vague or secretive charges, to extract political concessions from Western governments. An estimated 15 European citizens or dual nationals are currently imprisoned in Iran, including individuals from France, Germany, the UK, Sweden, and Switzerland.
Among the most high-profile detainees are French nationals Cécile Kohler, a teacher and union activist, and her partner Jacques Paris, who were arrested in May 2022 while traveling as tourists. This week, Cécile’s sister Noémie Kohler revealed that Iranian judges had handed the couple three serious charges: “spying for the Mossad,” “conspiracy to overthrow the regime,” and “corruption on earth”—a charge often used by the regime and punishable by death.
Despite Iran’s regime citing ongoing judicial processes, the French government maintains that the charges are baseless. A French diplomatic source told Radio France that if the accusations are confirmed, “they are totally unfounded.” The couple has reportedly been denied access to independent legal counsel, and their prolonged detention has been described by the French government as “inhumane” and tantamount to “torture.”
France Demands Release
French Foreign Minister Jean-Noël Barrot spoke with his Iranian regime counterpart Abbas Araghchi on July 6, reiterating France’s demand for the immediate release of Kohler and Paris. French President Emmanuel Macron had also raised the issue directly with Iranian President Masoud Pezeshkian, stating in a June 21 post, “Cécile Kohler and Jacques Paris must be released. Their inhumane detention is unjust. I expect them to return to France.”
The Iranian regime has not officially confirmed the latest charges, all of which carry the death penalty. Araghchi told Le Monde that the “judicial process is underway” and that consular access had been granted in accordance with Iranian law. On July 1, the chargé d’affaires from the French embassy in Tehran reportedly met with the couple during a scheduled visit.
Broader Implications
The Montrelos case—and the continued detention of Kohler and Paris—underscores growing concerns about travel to Iran amid escalating diplomatic tensions and internal repression. Human rights groups, including Hostage Aid Worldwide, have repeatedly warned about the regime’s strategy of detaining Western nationals as bargaining chips in nuclear or sanctions negotiations.
Despite international appeals, Iran’s regime shows little indication of shifting its policy. As Tehran continues to signal hostility toward the West and expand its use of judicial pressure tactics, the fate of detained foreign citizens—including Lennart Montrelos—remains uncertain.
Human rights advocates are calling for stronger international coordination to pressure Iran into releasing political prisoners and foreign detainees, warning that without consequences, the regime’s practice of hostage diplomacy will only continue to grow.
