The freak tragedy occurred some three minutes before the end of the match in Dunkirk last evening, when a player hit the puck -- a rubber disk -- towards the end of the rink and a teammate then diverted it, sending it into the stands.
Hugo, who was with his father, was hit on the ear and suffered cardiac arrest. Rescue workers on site were able to revive him, but he died today of his injuries in hospital.
"It's hard. Everyone knows each other, everyone knows the kid," said Dunkirk Mayor Patrice Vergriete.
Today afternoon, some 400 people -- including a lot of children -- gathered in front of the ice skating rink to lay flowers.
