The deputy Police Commissioner of Administration in Papua New Guinea, Tom Kulunga, has been suspended.
Police Commissioner Sam Inguba says Tom Kulunga has been suspended to allow an investigation into claims that Mr Kulunga had illegal gambling machines at his home.
The National newspaper reports police and Gaming Board officials arrested several Asians during a raid on the house in Lae two weeks ago.
Several horse-race machines and accessories were confiscated from the house along with a mint for manufacturing 20 toea coins, as well as a pistol.
Five Asians are now facing charges ranging from operating illegal gambling machines and over-staying their visas.
Mr Kulunga has been suspended for 21 days and the Assistant Police Commissioner of Logistics, Mathew Minok, has been appointed as acting Deputy Commissioner.
