Police in Solomon Islands have yet to find a weapon linked to the murder of Australian police officer, Adam Dunning.
The Commander of the Participating Police Force, Sandy Piesley, says despite two arrests so far in relation to the killing no weapon has been found.
Commander Piesley says neither of the two men being held in connection with the shooting had a weapon when police detained them.
Commander Piesley says the Regional Assistance Mission has carried out numerous raids since the death of Officer Dunning, who was shot during a routine patrol in the country's capital, Honiara.
She says the search for the guns is continuing.
