Terrifying footage has emerged showing the moment Kansas City fans fleeing after rapid gunfire was let off during the Chiefs Super Bowl Parade,  with officials now confirming 29 have been injured with nine of them believed to be children. 

Two gunmen opened fire inside Union Station moments after the team including Travis Kelce and Patrick Mahomes left the stage on what should have been a triumphant day for the city following the Chiefs victory on Sunday.

New video has since emerged showing what sounds like rapid gun shot fire being let off at the parade.

Other footage shows the moment a suspect is tackled by Chiefs fans, with one woman seen picking up what appears to be an assault rifle.

The group hauled the alleged gunman to the ground and then shouted ‘we got the gun.’ The men held down the suspect until cops arrived to detain him.

Children’s Mercy Kansas City said the hospital was treating 12 patients, including eleven kids, TMZ reported nine of which have gunshot wounds. Police have also confirmed that they have detained three people.

St. Luke’s Hospital of Kansas City received one gunshot patient in critical condition and three walk-ins with injuries that were not life-threatening, spokesperson Laurel Gifford said.

‘When you have this many casualties, it´s going to get spread out among a lot of hospitals so that you don´t overwhelm any single ER,’ she said.

In a press conference in the last hour, Police Chief Stacey Graves said: ‘We are working to determine if one of the three are the one that was in that video, where fans assisted police.’

Graves also said that firearms were recovered following the shooting, saying: ‘We have recovered firearms. I don’t have a number for you or a caliber.’

No charges have been announced, and police said no motive has been determined. Police have referred to the people in custody as being detained.

While Kansas City Fire Chief Ross Grundyson said that eight victims had immediately life threatening injuries.

Police evacuated the train station as huge crowds fled in panic after the shots rang out, with up to one million people expected to have descended on Kansas City for the parade.

Fans were seen scrambling from the scene, with several people wheeled away in stretchers.

A different man in a red hoodie was also pictured being arrested, although it is unclear if he was one of those involved in the shooting.

Graves said at a press conference around two hours after the shooting that officers sprang into action and quickly apprehended the gunmen.

‘Officers ran towards danger, and we thank them for that,’ she said.

‘I’m angry at what happened today. People should expect a safe environment,’ Graves continued, noting that over 800 law enforcement were stationed at the parade.

Police said they were releasing all of those inside Union Station around 15 minutes after the shooting unfolded, but ordered crowds to remain away from the area.

Around an hour after the shooting, people inside the nearby Westin Hotel were ordered to take shelter as police raced toward the hotel.

The incident came moments after superstars including the quarterback, Mahomes, greeted fans following the team’s historic 25-22 overtime victory over the San Francisco 49ers.

The team were on buses returning to Arrowhead Stadium when the shooting started.

A heartbroken Mahomes later took to social media offering his condolences. ‘Praying for Kansas City,’ he wrote.

‘White House officials have been in touch with state and local leaders, and federal law enforcement is on the scene supporting local law enforcement.’

The Chiefs said in a statement: ‘We are truly saddened by the senseless act of violence that occurred outside of Union Station at the conclusion of today’s parade and rally.

‘Our hearts go out to the victims, their families and all of Kansas City. At this time, we have confirmed that all of our players, coaches, staff and their families are safe and accounted for.

‘We thank the local law enforcement officers and first responders who were on scene to assist.’

Chiefs trainer Rick Burkholder said he was with coach Andy Reid and other coaches and staff members at the time of the shooting. Burkholder said the team was on buses returning to Arrowhead Stadium.

The NFL issued its own statement saying it was ‘deeply saddened’ and adding that its ‘thoughts are with the victims and everyone affected.’
