The Federal Bureau of Investigation has joined the Houston Police Department in their investigation into Travis Scott's Astroworld festival that occurred last November.

The crowd surged during the rapper's headlining set which led to the death of ten people - including a nine-year-old attendee, who died in the hospital as a result of his injuries.

The agency has created a website where attendees can upload footage of the event to aid in the investigation.

“Houston Police Detectives have already viewed countless hours of video evidence as part of our ongoing investigation into the Astroworld event,” HPD wrote on Twitter. “To ensure that we have captured all evidence for a complete investigation, we have partnered with the Federal Bureau of Investigation for additional technical assistance."

Specifically, the FBI is looking for video footage of the main concert venue from 8pm-11pm.

The US Congress has announced they will be investigating concert promoter Live Nation for its role in mismanaging the event.

The House Oversight and Reform Committee said, "the tragedy at Astroworld Festival follows a long line of other tragic events and safety violations involving Live Nation."

Over 275 lawsuits have been filed against the promoter, Travis Scott as well as fellow event performer Drake and other affiliated entities.

Scott has been accused of "inciting a riot and violence" during his set. He has responded to the claims saying that he is "devastated" over their deaths but, has not yet claimed any responsibility.
