French justice officials have launched an investigation after cycling champion Mathieu van der Poel had a plastic bottle hurled at his face during his triumphant ride to a third consecutive Paris-Roubaix victory on Sunday.

Dutch rider Mathieu van der Poel benefited from Tadej Pogačar’s late crash on Sunday to win the Paris-Roubaix race for the third straight year.

The Dutchman remained on his bike to secure his third successive victory at the race, also surviving a puncture with just 15km left.
