VIDEO shows the heroic moment fans tackled someone they believed to be a suspect in a mass shooting at the Kansas City Chiefs' victory parade.
Cops said three people were in custody after the shooting that killed one person and injured at least 22 others, including children, at Union Station.
Police said in a press conference that they are aware of the video and are looking into whether the person tackled is one of the three people they detained.
"I do want to comment on the question I got earlier about a video of some fans tackling someone," police said.
"We do have three persons detained and under investigation for today’s incident.
"We are working to determine if one of the three are the one that was in the video where fans assisted police."
Cops said at the briefing that they have not yet discovered a motive behind the shooting, which took place as a million people flooded the streets of Kansas City to celebrate the Chiefs' Super Bowl win.
The FBI created for people to send in tips or videos from the Chiefs parade to narrow down the suspect.
“FBI and KCPD are requesting any videos from the Super Bowl shooting and any video of shooters attempting to flee the scene,” the website said.
Horrific photos showed fans ducking for cover and jumping fences as they tried to escape the gunfire.
