The Samoan Deputy Prime Minister, Fonotoe Pierre Lauofo, has denied allegations that he interfered with police carrying out their duties.
The Samoa Observer received a letter from Fonotoe, who is out of the country, which denied any wrongdoing.
The paper had earlier published a leaked police report, in which an officer accused Fonotoe of telling another minister to drive away from police after they had asked him to undergo a breath test.
An Associate Minister Muagututagata Peter Ah Him was reported to have been stopped on suspicion he was driving under the influence of alcohol.
Last week, the Assistant Police Commissioner called for Fonotoe to be charged with interfering in a police matter.
On Friday, the Prime Minister Tuilaepa Sailele Malielegaoi said an appropriate decision would be made once police investigations are completed.
Fonotoe has strongly denied the allegations but welcomed the police investigation, saying no one in Samoa is above the law.
