French justice officials have begun an investigation after Mathieu van der Poel was struck in the face by a plastic bottle during his third consecutive Paris-Roubaix victory. The incident, which occurred while he was racing with 33km remaining, has prompted the UCI and his team, Alpecin-Deceuninck, to condemn the act as dangerous and unacceptable, with plans to take legal action against the perpetrator. The spectator has since surrendered to police, and further actions will be determined by the Public Prosecution Service.
