Iran’s exiled Crown Prince Reza Pahlavi was splattered with red liquid on Thursday as he left a building following a news conference in the German capital.
Despite the incident, Pahlavi waved to supporters before getting into a vehicle that drove away from the scene.
Police immediately detained the suspected perpetrator, though further details about the motive were not immediately available.
Pahlavi has lived in exile for nearly five decades following the overthrow of his father, Mohammad Reza Pahlavi, during the Iranian Revolution. The revolution saw millions take to the streets, forcing the shah from power.
In recent years, Pahlavi has sought to reassert his role as a political figure and position himself in discussions about Iran’s future
