DEVILS LAKE (AP) - Ramsey County authorities say they are investigating a woman's report that she was raped at a North Dakota National Guard camp near Devils Lake.

The sheriff's department's call log shows the woman went to the emergency room at Mercy Hospital in Devils Lake, which alerted the sheriff's department shortly after 4 a.m. July 11.

The log says the woman told deputies the incident happened at Camp Grafton and "that she remembers going back to her dorm, then waking up sore."

Camp Grafton is the Guard's training center five miles south of Devils Lake.

The Guard referred questions to the sheriff's department. Deputy Sada Sobolik said her department and the state Bureau of Criminal Investigation are looking into the allegation and declined further comment.
