SPAIN — Protesters jeered the Spanish king’s son-in-law before he was questioned Saturday by a judge about allegations he and a business partner funneled away millions of euros through fraudulent deals.

Inaki Urdangarin, who has not been charged with a crime, made his way into a courthouse in Palma de Mallorca amid tense street scenes, where a contingent of about 170 police kept several hundred protesters away from the building. Urdangarin, married to 75-year-old King Juan Carlos’ second daughter, Princess Cristina, has denied any wrongdoing.

The Duke of Palma, the title held by Urdangarin, had been called to answer questions privately at a courthouse about whether he used his high-profile status to secure lucrative deals for a nonprofit foundation he ran and then fraudulently diverted money for personal gain.

Judge Jose Castro questioned Urdangarin about three purported offenses against the Treasury, including corporate-tax fraud related to his foundation and matters linked to his personal income tax returns. Under Spanish law, the court will decide whether the prosecution has adequate evidence to file charges against the duke.
