Narrative:

GPS was being used in-flight by passenger. The air marshal observed him. He was very secretive when asked if he was using such a device. He denied using this. I followed up approximately 15 mins later and he did have a GPS. I ordered him to place it in his carryon bag and not to remove it until he deplaned.
