Authorities are investigating a riot that seriously injured three people and forced police to detain 120 others following Club Brugge’s 1-0 win against Antwerp.

The local police chief Dirk Van Nuffel said one officer was seriously injured as they sought to contain a brawl between Belgian fans reinforced by others who had come from the Netherlands.

All of those detained have been released but investigators are still trying to discover who was at the heart of the fighting. Van Nuffel said such hooliganism “hadn’t been seen for years”.
