The Navy is warning Pokémon Go fans to watch where you play, because you may be posing a security risk.

On Wednesday, Joint Base Pearl Harbor-Hickam posted a reminder to those on or near base.

“With the new Pokémon Go game app going viral, including many active duty military and civilian employees actively playing the game, it is important to understand the personnel risks and security issues this game could pose,” JBPHH said.

The problem is, officials say, electronic cameras — like those utilized by the virtual gaming app — aren’t authorized for use in restricted areas at Joint Base Pearl Harbor-Hickam or Pacific Missile Range Facility or near entry control points, or gates.

Violators could face administrative or disciplinary action.

Officials also urge drivers to stay alert, as they may encounter distracted gamers, and avoid traveling to potentially dangerous locations off-base.
