Breaking: Assault on One Nation volunteer not being treated as politically motivated

The assault of a One Nation volunteer on Victoria's Surf Coast is not being treated by police as politically motivated.

"Detectives are not treating the incident as politically motivated," a Victoria Police statement said today.

News of the assault emerged yesterday, with One Nation leaders alleging the attack was because the 60-year-old man had the party's signs displayed on his property.

Police today clarified the victim had been assaulted with "a blunt weapon", not a baseball bat as originally reported.

Since the incident, a 14-year-old boy and a 37-year-old man from Hampton Park have been taken into custody, with the man being charged with intentionally causing injury and other assault-related offences.

The 14-year-old was issued with a caution.
