Some rowdy soccer fans in Sweden were leaving a match Wednesday night. And apparently if you load too many people onto an escalator at the same time, the braking mechanism can fail.
Because there's a video of a few dozen people cramming onto a down escalator all at once. And it starts speeding up until it's going closer to ROLLER COASTER speed.
You can't see the end of the escalator, so it's not clear if anyone was hurt. But from how fast it was going, people must have been piled on top of each other at the bottom.
