Police say 11 children and the driver were aboard when 22-year-old Nicholas John Miller got onto the bus Thursday morning in Jacksonville, a Little Rock suburb.
Jacksonville police spokeswoman April Kiser says Miller was armed with a knife and pulled over only after seeing police spike strips on the road.
Kiser says no one was injured. She says it's unclear why Miller boarded the bus.
Miller was arrested on charges of vehicle piracy, kidnapping and aggravated assault. He hadn't been booked in the county jail by Thursday afternoon, and it wasn't immediately clear if he had an attorney.
