Grand Forks police are investigating the armed robbery of two out-of-town people staying at a local hotel.

Authorities say two men armed with a gun took an unspecified amount of cash from the victims at the Canad Inn about 3:30 a.m. Sunday. One of the victims suffered what police say were "very minor" injuries.

Authorities did not elaborate on the injury or say whether those involved in the incident knew one another.
