"Two gunmen" makes this sound like some kind of planned terrorist action, or some gang members doing typical gangbanger shit, but it could just be one shooter, and one good guy who shot at him, but was "detained" because, well, in situations like this, you arrest anyone who might be involved.

The Kansas City Chiefs Superbowl parade has descended into chaos with multiple people wounded in a shooting in the city's Union Station.

Stars including Travis Kelce and Patrick Mahomes were rushed from the scene as the shots were fired seconds after they left the stage.

Two gunmen have been detained, according to the police department. A man in a red hoodie was pictured being arrested, although it is unclear if he was one of those involved in the shooting.

Officers are now evacuating the streets surrounding the train station where up to one million people had gathered to celebrate the win.

Reports indicate up to 10 people may have been injured, although it is unclear how many sustained gunshot wounds or were hurt in the resulting chaos.
