A malfunctioning pyrotechnic display injured four people at the Summerland festival in Colombia over the weekend. Check out footage of the incident below.

As reported by El Tiempo, fireworks ignited part of the rigging of the main stage during DJ Nicky Romero's set, cutting his performance short whilst the fire was extinguished. Fellow DJ Dimitri Vegas was on stage at the time, and tweeted: "Half my crew and @wolfpack got impact burns all over their bodies and 2 even got rocket explosion on the ear."

The three day music festival, which saw sets from Afrojack, Armin Van Buuren and Cedric Gervais, faced even more disruptions after a reported 100 people were treated on the first night alone for adverse drug reactions, with El Tiempo reporting "hallucinogenic substances" being rife at the event. 

However, Summerland organiser Javier Alfonso Guevara has refuted the claims, telling El Universal: "Not all of the intoxications were due to hallucinogens. Many people who came to medical-treatment points did so because of dehydration, because they were moving constantly and had not ingested the necessary liquids."

Further upset was caused when Belgian DJ duo Dimitri Vegas & Like Mike were forced to cut their set short after 30 minutes by police officials instigating the 2.30am closing time mandated by officials, causing fans to take to the Summerland Facebook page to complain about the "ignorance" of the Cartagena police force.
