A swarm of bees settled on the bicycle of its owner, who had deposited it in the grass. A video broadcast on the Facebook group "Pirogue Baie de Somme" shows the bike covered with hundreds of bees.

The park has been evacuated. A beekeeper finally intervened to dislodge the bees from the bike. Once the queen was captured, all the bees left the bicycle and the park was evacuated. The phenomenon would not be so rare, explains Julien Chirache, a beekeeper quoted by "L'Éclaireur"
