"While we sincerely value the incredible ongoing support from our younger fans, we ultimately believe that Ultra Music Festival is a premium event geared towards adults," reads a statement on Ultra's Facebook page.

"This decision has been made to reinforce and promote the safety of all Ultra Music Festival fans and to ensure the overall enjoyment of all future attendees. We are extremely grateful for all the support we have received from our younger fan base to date, and we encourage them to attend the festival once they reach the appropriate age.

"Until then, our free YouTube stream, 'ULTRA LIVE' is available worldwide for everyone of all ages to enjoy and share in the Ultra experience."
