"Baran Arjmand, a 15-year-old member of Iran's youth national team who participated in the World Championships in Sweden, left the delegation after the competition concluded," the Iranian Table Tennis Federation said Friday.
"This young athlete, without notifying or coordinating with the federation, introduced herself to police in Copenhagen while the team was returning to Iran," the statement added, without describing her potential motivations.
Many Iranian athletes have sought refuge while abroad in international sporting competitions in recent years.
Forty percent of the 36 athletes selected for the 2024 Refugee Olympic Team hailed from Iran.
The considerable presence of Iranian refugees on the team followed a surge in the emigration of athletes, artists, and skilled workers from Iran, driven by increasing economic pressure and anti-government sentiment.
Despite having received her boarding pass for her flight home, Arjmand refused to return to Iran, a report by the Tasnim News agency affiliated with the Islamic Revolutionary Guard Corps said.
