AKRON, Ohio (AP) — Police in northeast Ohio say a student accidentally released the emergency brake on a bus that rolled back and killed the driver as she conducted an evacuation drill last month.

Akron police on Thursday said the 10-year-old ran to the back of the bus after releasing the brake. The driver, 51-year-old Laura Zborowski, tossed the student out of the way before the bus rolled over her. Zborowski has been hailed her as a hero for saving the child’s life.

The accident occurred Sept. 16 at Middlebury Academy, a charter school in Akron for children from kindergarten through eighth grade. More than 30 students who had been on the bus witnessed the accident.

Zborowski worked for a private bus company that transports 50,000 Ohio school children.
