South Wales Police attended a large gathering of people for an illegal rave in the Banwen area.
Some music equipment has since been removed after a section 63 notice was issued and two organisers have also been issued with fixed penalty notices for £10,000.
Police have also issued a number of section 59 orders for people using their vehicles in an anti-social manner.
Chief Superintendent Simon Belcher said “This type of illegal gathering is totally unacceptable and we are aware of the concerns it is causing for the local community.
“I would like to again remind people of their obligations under the current Coronavirus legislation and the overarching goal for everyone to take personal responsibility by following Welsh Government regulations to Keep Wales Safe.
“We have a number of resources in attendance including the police helicopter and roads policing officers.
“It has been estimated there are up to 3,000 people at the gathering who have apparently travelled from across the UK and we are looking at all pieces of legislation as to what action can be undertaken safely.
“Unlawfully parked cars will be dealt with and people who continue, despite our advice, to try and attend this illegal event area being turned away.”
Superintendent Jason James continued: “We have throughout the day had significant resources at the site and been engaging with the attendees and making every effort to engage with the organisers.
“Events of this kind are illegal and have a significant impact on the community. A number of people have left the site but there are still around a thousand people in attendance and we will continue to have resources at the location throughout the night.
“Those gathering know that their actions are irresponsible and we are working with other agencies and utilising the legislation available to us including covid-19 legislation but we need to ensure that any action taken is done so safely.”
