Reno County authorities are investigating reports of inappropriate photos being circulated at Reno Valley Middle School and Nickerson High School.

Sheriff Capt. Steve Lutz says authorities questioned students and confiscated phones at the schools. He said Friday the investigation is still open.

Someone notified law enforcement about the problem Wednesday, and investigators spent Thursday interviewing students and parents. Nickerson-South Hutchinson Superintendent Dawn Johnson said in a statement that the district is cooperating with the investigation.

Further details about the investigation have not been released.
