Wild video shows a UK bus-stop roof suddenly collapsing as carnival-goers twerk on top of it, leaving several people injured.

The terrifying collapse Sunday at London’s Notting Hill Carnival came hours after a police horse died at the annual street party, which returned this year for the first time since its two-year hiatus because of COVID.

Now-viral footage of the bus-shelter collapse shows a scantily clad woman initially alone atop the structure, sticking out her tongue, swinging her arms and twerking to the screams of those below.

Around 10 other people then join her on the roof — a wild scene filmed by people packing the streets of the upscale neighborhood famed for Hugh Grant’s 1999 rom-com “Notting Hill” with Julia Roberts.

Onlookers then gasp in collective horror as the roof suddenly collapses — slamming into several people walking underneath as those on top also tumble down.

London’s Metropolitan Police confirmed that officers responded to the collapse — but amazingly, only “two people sustained minor injuries,” the force said, stressing that those hurt did not need further treatment.

Within minutes, the same area was again bouncing with dancing carnival-goers, according to a clip shared by one of the onlookers who filmed the collapse.

An hour after confirming the accident, police also revealed that a police horse had collapsed at the carnival late Saturday.

“Officers provided emergency care, but the horse sadly died at the scene,” police said.

“It is too early to determine the cause of death,” insisted the police, who noted that “officers form a very close bond with the animals they serve alongside.”
