Police are asking members of the public and landowners across Norfolk to report any suspicious activity during this bank holiday weekend in an attempt to foil illegal raves.

They're also warning anyone thinking of organising an illegal rave or unlicensed music event (UME) that sound equipment could be seized and that prosecution could also be on the cards.

Chief Superintendent Nick Davison said: 'Historically we have seen illegal raves and UMEs being held over bank holiday weekends. These events are not only potentially dangerous, they also cause unnecessary damage and disruption.

Police will be paying special attention to social media but are asking locals to pay particular attention to any suspicious goings on around open land or disused buildings. Landowners are also being reminded to keep property entrances as secure as possible.

Here's what to look out for:

- Vans, lorries or large numbers of vehicles gathering near woods, rural car parks or near to disused buildings/warehouses

- Fliers advertising raves

- Broken padlocks on access gates to areas where a rave may take place

Chief Supt Davison continued: 'Reliable and timely information about where and when an event is being set up can help us prevent it.

'If we receive the information when the event is already underway, we may instead monitor it to ensure as far as possible the safety of those in attendance. Vehicles trying to get on or off site will be stopped and dealt with for any offences they might be committing. Where possible the organisers will be identified and dealt with at the end of the event, which will be closed as soon as it is safe to do so.'

Anyone with information should contact Norfolk Constabulary on 101.
