At least eight people died and over 300 were injured during a stampede at rapper Travis Scott’s Astroworld Festival in his hometown of Houston, Texas on Friday night.

8 people, including a 10-year-old boy, were pronounced dead at area hospitals. 23 others are hospitalized.

Police say the dead and injured were trampled when 50,000 people surged over barricades at the front of the stage on Day 1 of the sold out music festival at NRG Park.

Officials referred to the incident as a “mass casualty event” during a press conference on Saturday morning.

Houston Police Chief Troy Finner said authorities have “heard rumors of people injecting people with drugs” at the show, but added “I think it’s very important that none of us speculate.”

A source close to concert organizers told the NY Post:

“This was a targeted attack on innocent people, including a child. People were being spiked against their own will. The crowd surge was from panic because people were running for safety.”

Scott and fellow rapper Drake were performing onstage at the time of the fatal stampede around 9 p.m. on Friday, Nov. 5.

Angry fans took to Twitter to criticize Scott for not stopping the concert as his fans lay dying.

Footage shot at the scene shows paramedics performing CPR on unresponsive fans on the ground.

Social media influencer and reality star Kylie Jenner and her thee-year-old daughter, Stormi, both attended her boyfriend Travis Scott’s concert. Kylie’s sister, model Kendall Jenner, was also backstage. They were not injured.

The 29-year-old “Sicko Mode” rapper, real name Jacques Webster II, is best known for his hit singles “Antidote”, “Mafia” and “Escape Plan” and for fathering two children with Kylie, 24.

Day 2 of Scott’s Astroworld Festival has been canceled.
