The Breitling watch worth several thousand euros was among several items recovered from a suspected thief who was arrested during the fiasco that marred the match between Liverpool and Real Madrid.
As fans massed at the Stade de France stadium just north of Paris, organisers kept thousands out because of suspected fake tickets, creating bottlenecks at entry gates that prompted police to fire tear gas and pepper spray.
After the game, supporters were preyed on by robbers as they made their way to local transport connections, with many reporting pickpocketing, muggings and threats.
“In one operation on the night of the final, several objects that clearly had been stolen were seized. Investigators were able to identify the owner of a luxury watch,” prosecutor Eric Mathais in the Paris suburb of Bobigny said on Twitter.
“Contact was established with him and, during a visit to France, he was able to recover his watch at the Bobigny courthouse on Tuesday,” he said.
Around 240 complaints have been filed with police over the violence, which sparked concerns over the French authorities’ ability to ensure security at two major upcoming events, the Rugby World Cup next year and the 2024 Paris Olympics.
“I’m hopeful that some of the perpetrators of these aggravated robberies will be identified and judged,” Mathais said.
An enquiry by the French Senate into the mayhem concluded last month that organisers were to blame, not supporters, undermining claims by the police and Interior Minister Gérald Darmanin.
Paris police chief Didier Lallememt has since been replaced.
