What did the bus driver do with the doors before police arrived?

The bus driver kept the doors closed until police arrived to maintain the safety and security of both the passengers and the vehicle. This action helps prevent any potential issues that could arise from allowing unauthorized access while waiting for law enforcement to address the situation. Keeping the doors closed can also help to establish a controlled environment, ensuring that only police and other emergency personnel can enter when they arrive, which is crucial during situations that may involve safety concerns or ongoing investigations. By securing the bus in this manner, the driver prioritizes the well-being of all individuals onboard.
