Kansas City police have reported arresting both of the alleged shooters following an alarming incident at the end of the Chiefs Super Bowl victory parade on Wednesday.

What began as a festive celebration has ended on a very sad note as one person is believed to have been killed while nine others were injured after a shooting broke out at the event.

The video shown below shows a man in a red jumpsuit being led away in cuffs. As to whether or not he’s one of the shooters is still unclear, however.

A photo shows another male seated on the ground while appearing to have his hands cuffed at his back while an automatic weapon is also shown on the ground in a separate image.

NBC News reports that “officials believe the shooting is criminal in nature but is not initially believed to be terrorism.”

Meanwhile, the Chiefs have put out a statement noting that all of their players, coaches, and staff are safe and accounted for while quarterback Patrick Mahomes and linebacker Drue Tranquill have both offered reactions on social media.

The NFL hadn’t made an official statement at the time of writing.
