A bus carrying primary students home from school in Chattanooga, Tennessee, crashed on Monday afternoon, killing at least six children and sending nearly two dozen to a hospital with injuries, authorities said.
The driver, identified as Johnthony Walker, 24, was taken into custody and faces five counts of vehicular homicide, reckless endangerment and reckless driving charges, USA Today reported.
Speed appeared to have contributed to the crash, Chattanooga Police Chief Fred Fletcher said.
Five children were found dead inside the vehicle, which normally carries 35 passengers, and a student died at a hospital, said Melydia Clewell, spokeswoman for the Hamilton County District Attorney's office. It was not clear how many students were in the bus when it crashed.
The students were in kindergarten through fifth grade, she said, which would make them roughly aged between five and 10.
The crash left the bright yellow school bus wrapped around a tree, mangled and nearly severed in two. Rescue teams were still sifting through the wreckage, hours after the crash.
Transport investigators were also opening a probe into the crash, and planned to send a team to Chattanooga on Tuesday, the National Transportation Safety Board said.
School officials had not found any complaints filed against the driver, Clewell said.
Two bloodied students were lying on stretchers in a front yard receiving attention from first responders nearly an hour after the crash, while others not taken to the hospital appeared dazed with cuts on their faces, the Chattanooga Times Free Press newspaper reported.
Asked about the crash after a hearing in Nashville, Governor Bill Haslam said the state would offer its assistance.
"It's a sad situation anytime there's a school bus with children involved, which there is in this case," he said.
