As some of the music industry's biggest acts head to Sundown Festival at the Norfolk Showground this weekend, police are urging festival-goers to stay safe.

With more than 40,000 people expected to visit the festival police are reassuring revellers that police patrols will be in place.

Music lovers are urged to keep their personal belongings safe and to behave responsibly.

Chief Inspector Nathan Clark said: 'We have taken the practical and precautionary decision to provide patrols outside the Norfolk Showground.

'Whilst Norfolk is a safe county, this additional policing is about providing a visible reassurance to the public and being ready to respond.

'Security guidance will be issued by the event organisers and I would encourage the public to adhere to this advice and be aware that you may be subject to searches.

'Please arrive with plenty of time to allow for extra checks to take place and to ensure you get access to the venue before the event begins.'

Sundown Festival returns to the county on September 1 till September 3, and for 2017 is set to be 'bigger and better than ever' according to organisers, with the addition of two new stages, bringing the total to five.

'My advice to those camping is to only bring items that are essential and think about security of valuable items, particularly mobile phones,' Chief Insp Clark added.

'This is a fantastic event and we want everyone to have an enjoyable time.'

Festival-goers are also being reminded to be sensible when it comes to drinking alcohol and warned about the dangers of taking illegal drugs.

Chief Insp Clark added: 'We would advise anyone drinking alcohol at the festival to be sensible, know your limits and to stay with friends.

'Anyone found to be drinking alcohol underage could be asked to leave the event.

'It is an offence to supply them or to have them in your possession with the intent to supply. People will be searched on entry to the site and anyone found in possession of illegal drugs or psychoactive substances will be ejected from the festival and may face police action.'
