Police are trying to figure out how a school bus carrying students crashed into a tree Thursday evening.  

West Virginia State Police said the bus was taking 40 student athletes and coaches to an event. They were on their way from Buckeye Local High School in Rayland, Ohio, to West Liberty University in West Virginia to watch a football practice, the Associated Press reported.

The bus then went off of the road into a ditch, and the rear of the school bus slammed into a tree along the road, state police said in a statement.

State police added that the injuries were non-life-threatening. One person on the bus was in the ICU for multiple fractures, The Intelligencer reported, adding that several bus windows were broken.

The Intelligencer said many of the students’ parents arrived at the scene of the crash, and that another bus came soon after the crash to transport the uninjured students.

Police said they believe speed could have been a factor, but that an investigation is ongoing. 

The Intelligencer reported that the driver had been cited.
