Students at Sherwood Elementary School are back in their classrooms. This comes two weeks after fire destroyed the school`s cafetery and auditorium. Investigators say arson is to blame. The cafeteria will not be open, so the districe will provide students with box lunches for the remainder of the school year. Classes were temporarily held at North Little Rock First Assembly of God until the school could re-open. Police are still trying to determine who started the fire.
