American Samoa police chief William Haleck is appealing to the public for help in finding the people who shot at the Leone police substation early Saturday morning.
Two officers were inside the station at the time of the shooting and one was nearly struck by a bullet.
Mr Haleck has called the shooting a cowardly act on those who are in public service, who have sworn to serve and protect the community .
"People of American Samoa should be highly disturbed and offended by this cowardly attack. This is an unprecedented act that has never happened in American Samoa."
