Angry and opportunistic ticketless fans breached gates at the 2015 Wireless Festival at London's Finsbury Park, with one video showing a lone police officer and a group of Showsec security guards being attacked by a mob trying to gatecrash the event during Lethal Bizzle's performance.
A spokesperson for Wireless later told metro.co.uk: "This was an isolated incident that was dealt with quickly where no-one was hurt and the perpetrators were removed on an otherwise hugely successful first day."
"Organisers of Wireless Festival take security very seriously and work closely with ShowSec Security, Local Police and other agencies to put procedures in place to ensure the event maintains an enjoyable and secure environment for all its customers."
Friday’s Wireless saw Lethal Bizzle joining a line-up which also included A$AP Rocky, Labrinth, Nero, Duke Dumont and Major Lazer, as well as headline act Drake.
Avicii, Kendrick Lamar, Mary J Blige and Childish Gambino are among Saturday’s acts, while David Guetta and Nicki Minaj will be among those taking to the stage on Sunday.
A Wireless spokesperson has told Metro.co.uk that security has been increased for the final day.
Chief superintendent Victor Olisa, borough commander for Haringey, said: “The Wireless Festival has been held in Haringey for a number of years and is enjoyed by thousands of people. Unfortunately, this weekend we saw a number of people act in an unacceptable manner by trying to barge their way into the festival without paying. While the number of arrests over the three days was low – and mainly for minor offences – we will review footage of this incident and decide whether any action should be taken against those involved.
“I would like to take this opportunity to praise the actions of the officer, and the security team, who managed to control the situation without it spiralling out of control. This is yet another example of the difficulties faced by officers performing their duty.
Officers made 23 arrests between Friday, 3 and Sunday, 5 July for a number of offences including possession of an offensive weapon, breach of bail and drugs offences.
