At about 11.30pm police identified a 21-year-old Casey man in Civic in breach of his bail conditions.

While resisting arrest, the man became aggressive and allegedly headbutted and kicked an officer.

He is  charged with resisting territory public officials and assaulting a frontline community service provider.
