The rappers Travis Scott and Drake have been sued for having “incited mayhem” after eight people were killed and dozens injured in a crush during a Texas concert, a law firm has confirmed. Thomas J Henry Law tweeted a story published by the Daily Mail on the lawsuit, confirming on Sunday that it had filed “one of the first lawsuits in Travis Scott Astroworld festival tragedy”. The plaintiff is 23-year-old Kristian Paredes, who was one of those “severely injured” at the concert on 5 November. Another lawsuit was filed in the state court of Houston on behalf of a man injured in the crush. Attorneys for Manuel Souza sued Scott, the concert organisers Live Nation and others, claiming they were responsible. In a tweet posted on Saturday, Scott said he was “absolutely devastated by what took place”. He pledged to work “together with the Houston community to heal and support the families in need”. About 50,000 people were in the audience at NRG Park in Houston when the crowd started pushing towards the stage as Scott was performing, triggering chaotic scenes. Paredes, a Texas resident who is also suing Live Nation and the venue, “felt an immediate push” at the front of the general admission section as Scott got on stage, the complaint says. “The crowd became chaotic and a stampede began. Many begged security guards hired by Live Nation Entertainment for help, but were ignored.” The lawsuit, filed in Harris county court in Houston, claims Scott “had incited mayhem and chaos at prior events” and “defendants knew or should have known of [Scott’s] prior conduct”. It accuses the Canadian rapper Drake, who joined Scott’s headline set, of contributing to causing the surge towards the stage. “As Drake came onstage alongside Travis Scott he helped incite the crowd even though he knew of Travis Scott’s prior conduct,” the complaint says. He continued to perform even as the “crowd became out of control” and the “crowd mayhem continued”, it adds. Details of those who died have begun to emerge. One of the victims was reported to be Brianna Rodriguez, 16, a student at Heights high school in Houston described by her family as “beautiful” and “vibrant”. Meanwhile, Danish Baig, 27, reportedly died while attempting to save his fiancee. Franco Patino,a student at the University of Dayton in Ohio, and his friend Jacob Jurinek, both 21, also died. They had saved up to go to the event together. The youngest of five siblings, Rudy Pena, 23, died after he attended the concert with his friends. His sister told the Laredo Morning Times he was “the sweetest person” and a big Scott fan. Survivors described seeing people squeezed against one another and many struggling to breathe. Scott, who launched the Astroworld music festival in 2018, reportedly halted his act several times when he saw fans in distress near the stage. Authorities in Texas launched a criminal investigation into the tragedy, involving homicide and narcotics detectives, the Houston police chief, Troy Finner, said on Saturday. The Houston mayor said authorities were looking at video footage and talking to witnesses, concert organisers and people who were hospitalised. Sylvester Turner said the eight killed were aged between 14 and 27, with one person’s age unknown. The incident also resulted in 25 people being taken to hospital and more than 300 others treated at the scene for minor injuries.
