Omaha police say a medical technician has been arrested on suspicion of sexually assaulting three women as they were undergoing ultrasound testing.

Police reports indicate three women -- ages 27, 55 and 64 -- reported being sexually assaulted by a technician at Omaha facilities in September, October and December. The women told police the assaults happened as they were having ultrasounds performed on their chest, abdomen and legs.

Police say 27-year-old Kevin Ryan, of Ralston, was arrested Wednesday morning with his attorney present. He faces three counts of first-degree sexual assault.

Police did not name Ryan's attorney, and Ryan's case had not been listed among online court records by Wednesday afternoon.

A public phone listing for Ryan could not be found.
