Suffolk Police is planning extra patrols in a crack down on illegal raves over the New Year period.
The force has said it will adopt a zero-tolerance approach and is asking people to report suspicious behavior and to look out for signs of unlicensed events taking place.
Officers find it much harder to shut down a rave once it has already started so they say the force is trying to take preventative action.
