UPDATE, 11AM: MORE than 2000 revellers at an 'unauthorised rave' in Newton Boyd, where a 24-year-old man from Green Pigeon was found dead yesterday, are not expected to leave the property until the event finishes this afternoon.
Coffs/Clarence crime manager Detective Inspector Darren Jameson said that while the investigation into the man's death was still in early stages, drug overdose was being look at as a possible cause.
"At this stage we are investigating his death being connected to a drug overdose," Det Insp Jameson said.
"Forensic examination found items consistent with cannabis use as well as other drugs at the scene, but we are still in the early stages of the investigation and the cause of death will be determined by the Coroner at a later date."
It is believed the man, from a remote area north-east of Kyogle, had attended the rave with a number of friends who discovered his body in a vehicle about 1pm yesterday.
Det Insp Jameson said the vehicle which contained the deceased was located within 200m of the event stage.
Whilst police were at the scene yesterday some patrons were aggressive and quite overtly unimpressed about the police presence.
Police at the scene asked the organisers to close the dance party down due to the man's death and safety concerns, but were refused.
Because the event, advertised on Facebook as the Omega Festival, is being held on a private property there is little police can do to stop it unless they receive noise complaints.
"We believe the property owner is aware of it but didn't come forward to police and could not be located," Det Insp Jameson said.
"There are a number of concerns we have including the safety of police and patrons. Whilst police were at the scene yesterday some patrons were aggressive and quite overtly unimpressed about the police presence.
"Events like this are shown to be drug and alcohol fuelled, and there's a significant amount of risk in putting those people back on the streets and on the roads."
The rave, which began on Saturday, is expected to finish at 4.30pm today.
It is believed the event was the same one police shut down on Thursday, while it was being set up on an Aboriginal Reserve in Tabulam.
A post to the Omega Festival Facebook page on Friday thanked hopeful attendants for their patience and said the event had been moved.
"Despite our best efforts police have forced us from the property. We are left with no option but to relocate the festival, directions for the new site will be emailed to ticket buyers during this evening, please do not post the new directions to Facebook."
