Law enforcement officials are looking for the person who flew a drone over Fenway Park during a Red Sox game.
It happened Thursday night during the late innings of a baseball game.
Federal Aviation Administration regulations prohibit unmanned aircraft systems from flying over stadiums during events.
They are never allowed to fly within five miles of an airport or more than 400 feet high anywhere.
The company that makes the drone says it has a geo-fencing system that forces users to comply with these regulations, but the user must have overridden it.
