A 27-year-old Circular Head man has been charged causing grievous bodily harm in relation to an assault on an Arthur River man at his home on Australia Day.
The arrest followed a protracted investigation by detectives from Western CIB.
The man will appear in the Smithton Magistrates Court at a later date.
``It is alleged that the 48 year old victim was assaulted at the front door of his residence and suffered severe head injuries in what was a targeted attack,'' Detective Senior Sergeant David Chapman said.
Inquiries into the incident are continuing.
Police encourage anyone with information that may assist in relation to this incident to contact them on 131 444 or through Crime Stoppers on 1800 333 000.
Detectives say the matter is not connected to the murder of Simon Crisp at Marrawah in the early hours of July 13, which remains under investigation.
