LAYTON — Police believe they have apprehended a man who twice exposed himself to a teenage custodian on school grounds.

The arrest was made after Layton police aired video of the man. With help from the public, they tracked him to a local address, according to a news release.

The flashing incident occurred Oct. 28 after the man had been in the school five hours, according to police reports. Cameras picked up his image in several areas of the school, even showing him trying to enter a girls locker room.

The female custodian, who had been mopping floors at the time, reported the incident the next day.

Arrested was Cody Moon, 23. He is being held on suspicion of lewdness, criminal trespass and interfering with a school.
