An officer with the Anchorage Police Department is facing wire fraud charges after an investigation revealed that he and a senior executive with Conoco Phillips allegedly defrauded the oil company for millions of dollars, officials say.

According to Alaska Public Radio, Forrest Wright and Nathan Keays—the Conoco employee and the Anchorage officer, respectively—reportedly created a scheme in which payments would be made to a company called EcoEdge for services never rendered.

Wright allegedly established the company as a vendor to ConocoPhillips and instructed Keays on how to submit fraudulent invoices.

Following a probe by the FBI, prosecutors filed charges on Wednesday.

Anchorage PD placed Keays on paid leave in December after learning of the allegations. He is now on unpaid leave.
