Police intervened after clashes between rival ice hockey fans in Lausanne.
Trouble broke out at the Vaudoise Arena around half an hour after Friday’s playoff game between Lausanne and Genève-Servette.
Witnesses say a loud bang, believed to be a firecracker, was followed by insults between fans.
Some Geneva supporters then made their way onto the ice, leading to physical confrontations.
Police used pepper spray to separate the groups, preventing further escalation.
