Rapper Travis Scott and organisers of the Astroworld Festival are facing legal action after a crowd surge at the concert in Texas on Friday night left eight people dead and hundreds injured.
The first of many expected lawsuits has now been filed over the tragedy, Billboard reports.
The lawsuit was filed on behalf of injured concertgoer Manual Souza in the Harris County District Court.
Mr Souza is seeking more than US$1 million in damages for what his lawyers are calling gross negligence and name Scott, organiser ScoreMore, and concert giant Live Nation as defendants.
The lawsuit claims the disaster was the direct result of “a motivation for profit” at the expense of safety.
Representatives for Scott, Scoremore and Live Nation did not immediately return requests from Billboard for comment about the lawsuit.
The news comes as more details of the victims who died in the tragedy come to light.
A 14-year-old boy and a man who was trying to save his fiancée are among the eight to lose their lives as a result of events at the festival, which is under police investigation.
Family and friends have paid tribute to those who died.
An emotional Scott posted a video message to Instagram on Sunday, saying he was devastated by the tragedy and his team was trying to get in contact with the families of the victims.
“I just want to send out prayers to the ones that was (sic) lost last night,” he says.
“You know my fans … really mean the world to me and I always just really want to leave them with a positive experience.
Scott said he and his team were working with the police and fire department, to “help us figure this out” and he asked anyone with information to come forward.
Officials said seven of the victims had been identified. Most of the victims were young people, with the youngest just 14.
Here is what is known about some of the victims so far.
