Four people were treated for minor injuries.

Lil Pump performed on top of his tour bus last night, after a smoke flare was reportedly set off during his performance in Nottingham.

Police confirmed that at least four people were being treated for minor injuries after the incident took place at Rock City on Friday.

In a statement, the venue confirmed the evacuation of the venue and claimed that it may have been pepper spray.

Nottinghamshire Police said they were called to the incident after “what is thought to be a smoke flare or similar having been set off inside the venue”. An investigation has been subsequently launched.

“The venue has been evacuated and officers are assisting with this to ensure public safety”, a police statement confirmed.

“Our medical and fire colleagues are on scene and are treating a number of people for minor injuries.”

A statement from Rock City said: “Putting the safety first of everyone attending tonight’s show, we’ve taken the decision to end the show as it is suspected that pepper spray was let off inside the Main Hall.

“We evacuated the building and are currently working with the fire service to ensure the building is safe to re-enter and that anyone who may have been affected got immediate treatment.”

Although the rapper is yet to directly respond, he later continued the show in the venue’s car park – with videos showing him performing his Kanye West collaboration ‘I Love It’ while atop his tourbus.
