(CNN) — At least two people died and 23 were injured at the South by Southwest interactive and music festival in Austin, Texas, county medical officials said, who responded to reports that a car had plowed into a crowd.
The car ran a barricade, police told CNN affiliate KXAN.
Ten of the injured were taken to hospital. Five were in serious condition. Police have apprehended the driver, KXAN reported.
