CENTENNIAL, Colo. — The Arapahoe County Sheriff’s Office said it arrested a man suspected of sexually assaulting a young girl in a public restroom inside a Marshalls store.

Ethan Humphries of Denver is suspected of following a young girl into a women’s restroom at the store near the intersection of University Boulevard and Arapahoe Road in Centennial.

After entering the restroom, Humphries allegedly crawled under the stall the girl was using. He then exposed himself and made the girl touch him, the sheriff’s office said.

While the incident happened in Centennial, investigators suspect the girl is not the only victim in the Denver metro area. They believe Humphries has been active in the area.

Anyone with information is asked to contact the sheriff’s office at 720-874-4026.

Authorities said they have not released a photo of Humphries because there remains a possibility of photo lineups and other identification techniques.
