The four-day Wireless Festival in London sees tens of thousands of people every year, and by the looks of the video above, a few ticketless guests decided to join in on the fun as well.

Hundreds gathered near a side gate at the festival as two security personnel tried their hardest to keep it closed. As they clearly grew restless, a concertgoer lifted the lock on the gate and chaos immediately ensued. Towards the end of video, one man appears to get tackled by security, something they all seemed to fail at with the hundreds of other crashers who got pass.

Watch the hysteria unfold above.
