Law enforcement located “a significant quantity of suspected cocaine” on an international plane that landed at Ohio University’s Gordon K. Bush airport in Albany on Wednesday, according to an OU Police Department news release.

The plane landed at about 2:30 p.m. Wednesday, and the pilot told police mechanical problems forced him to land. The Department of Homeland Security warned OUPD of the plane’s arrival, and Customs and Border Protection requested OUPD detain the plane’s two occupants. Gordon K. Bush Airport is not a port of entry, so international flights do not regularly land there.

The plane is a privately owned Canadian airplane based in Lachute, Quebec, according to information from the Canadian Civil Aircraft Register database.
