Police arrested 10 people, including two protest organizers, Sunday outside Melbourne’s Parliament House during a planned protest against Australia’s coronavirus response efforts, according to a statement obtained by CNN from Victoria Police.

The Victoria Police stated that protesters were in “direct contravention of the chief health officer’s current directives” regarding large gatherings and social distancing.

Three protesters were charged with assaulting a police officer, and one officer was taken to hospital for an apparent “rib injury.”

The police will continue to investigate the incident to identify those in attendance with the intention of issuing additional fines, the statement added.
