POLICE seized a makeshift weapon made out of the bill of a saw fish following a disturbance near Karratha overnight, in WA's far north west.

Police were called around 10.30pm last night to Stewart Court, Millars Well, west of Karratha, 1500km north of Perth, in response to reports of a disturbance involving a man armed with a sword.



The man, 32, wasn't armed when police arrived but was abusive and aggressive towards both the officers and members of the public.



``Because of his behaviour, he was advised he was being arrested,'' a police spokesman said.



``As they've tried to move him to the police car, he's struggled violently and one officer was kicked in the head, but they still managed to place him in handcuffs and secure him in the car.''



A search of the area uncovered the unusual weapon, which was described as 45cm long and very sharp.

Police are now looking into what charge would apply for possession of the weapon.

Police spokesman Samuel Dinnison said the weapon consisted of the snout part of a saw fish, which is about 45cm long, attached to a wooden handle.



The man was subsequently charged with assaulting a public officer, obstructing police and disorderly behaviour in public.



The makeshift weapon was seized by police and will be disposed of.

The man is due to appear in Karratha Magistrates Court today.
