Police have said they are “disappointed” following a number of incidents at the Red Hot Chili Peppers concert in the Hunter Valley last night.

NSW Police said the behaviour of some of Chili’s fans was “unacceptable” and that being drunk is no excuse to break the law. The police said an entire bus load of people had to be turned away and dozens were booted from concert grounds, with one man shooting snot on an officer as he was ejected from the festival for intoxication.

Fans of the seminal nineties band flocked to the Hope Estate winery for the event which began yesterday about 2pm and continued on until 10.

Attendees weathered rain to see the band perform outdoors and footage posted online suggests many enjoyed the show by the veterans of pop rock.

But police were out in force with officers from the Hunter Valley, the Northern Region, licensing officers and the dog units monitoring the event.

Police said six people were charged with a range of offences including common assault, assaulting police, resisting arrest and fail to quit.

About an hour before the concert ended, security asked a 25-year-old man to leave because he was intoxicated.

Police stepped in to assist the guards and the man allegedly refused to follow direction. Officers escorted the man from the premises and the man from Kensington blew snot at the constable.

“Our officers were kept busy last night with several drug and alcohol-related incidents,” said Superintendent Chad Gillies, Hunter Valley Police District Commander.

In a statement he said while most people there behaved well he was disappointed that so many had to be ejected for their intoxicated.

“Police are not there to spoil people’s fun, but the behaviour of people affected by alcohol was unacceptable and a music event is not an excuse to break the law.

“In one incident, security officers refused entry to a bus with 20 patrons on arrival due to intoxication levels,” Supt Gillies said.

He was taken to Cessnock Police Station and charged with assaulting an officer in execution of duty and excluded person fail to leave premises when required. He’ll appear in Cessnock Local Court on March 20.

Police and security kicked 79 people out of the concert for being too inebriated. 34 people had to be moved to a different area inside of the winery due to their level of intoxication.

Police also issued three criminal notices for trespassing.

Police also refused an entire bus arriving at the show with 20 people because of the levels of intoxication.

As part of the operation police found 44 individuals with MDMA, cocaine or cannabis. They also issued 17 cannabis cautions.

NSW police are under more pressure to show force at large music events following overdoses of five young people over the Summer months at music festivals.

Changes to licensing set to be introduced on March 1 will mean that music festivals and larger concerts that run for more than five hours will see more police presence along with mandatory services on site like ambulances and “chill-out” spaces.
