FAIRBANKS, Alaska — A school bus transporting elementary school students here was forced to stop in the middle of the road during an apparent road-rage incident last week, the Fairbanks Daily News-Miner reports.

Sharice Walker, a spokesperson for Fairbanks North Star Borough School District, told the newspaper in an email that the bus was carrying 17 students home from an afterschool program. A vehicle stopped in front of the bus, and the occupants of the vehicle allegedly got out to shout at the bus driver, take pictures, and then got back in the vehicle to follow the bus along its route, according to the Daily News-Miner.

Alicia Lewis, the interim principal of Ticasuk Brown Elementary School, said in an email to parents about the incident, according to KTUU, that the bus driver kept students on the bus until parents arrived, and that state troopers were also called. Lewis added in the email that a monitor was placed on the bus the next day as a precautionary measure.

Chris Kemper, a spokesman with First Student Group, told the Daily News-Miner that the driver “acted admirably,” adhering to training and protocol standards. He also added that, in general, the first thing a driver should do is call dispatch for assistance, and then do “whatever is necessary to maintain the safety and security of the students” should dispatch not be available.

An investigation for the suspects involved in the incident is ongoing, the newspaper reports.
