Police have arrested a visitor for the unauthorised flying of a drone.
It is illegal to operate a drone above or around the course during racing.
A post from the Constabulary said: “We made it as far as race week without an arrest for unauthorised use of a drone. For one visitor today during the Superbike Race, they chose to end their day today in a cell for unauthorised flying of a drone.
“Remember, there is a no-fly zone in place whilst the airspace is active. It’s for the safety of aircraft operating around the course, competitors, spectators and officials alike.”
