Portland Police are investigating reports of 'inappropriate touching' by a male student on a Skyline K-8 School bus.

Police say two female students reported the incidents, in December and January. Because the girls are younger than 14, the child abuse team is conducting the investigation and no other information can be released.

Police say the male student is under investigation. They have not released his age or other information.

School officials at Skyline, 11536 N.W. Skyline Blvd., are cooperating in the investigation, police say.
