Guam's tax department has asked the island's chief of police for support in exploring the possibilites of corruption at the agency.
The deputy director of the Department of Revenue and Taxation, Marie Benito, says the department is currently looking into whether there are employees compromising their duties for personal gain.
However, the Pacific Daily News reports that neither she nor the police department could provide details of the investigation.
Last week, two compliance inspectors were among 10 people charged by federal authorities for accepting bribes from local bar owners and conspiring to import cigarettes tax-free.
