Extra measures are being put in place to stop unlicensed and illegal raves taking place in South Wales this bank holiday weekend.
Gwent Police said such events have become easy to organise through social media and can often cause large-scale disorder, criminal damage with substance misuse taking place.
Officers are asking people to be aware of the signs of an illegal event taking place in their area ahead of the May bank holiday weekend. Such signs include posters on social networking sites, security on fields being tampered with and unusual volumes of traffic.
They can usually turn anti-social with large-scale disorder, criminal damage and substance misuse taking place.
Signs to look out for:
Posters or messages on social media advertising a rave
Locks and chains on fields and private land being cut or tampered with
Unusual traffic activity - i.e. large convoys of cars on quieter/rural roads
Sound equipment and marquees or tents being set up
Power generators being hired and bought onto land/rural locations
Flattened or disturbed hedgerows
Loud music and sound checks in locations where this would not be expected
