Motorist and gun-toting school bus driver tangle on expressway

A school bus driver and a motorist were detained following a road rage incident Thursday in Center City, state police said.

The incident happened in the westbound lane of I-676 (Vine Street Expressway) near the Broad Street exit around 3 p.m.

Authorities said the driver of a BMW sedan pulled to the shoulder to confront the bus driver, who he claimed was tailgating. When the BMW driver attempted to board the bus, the bus driver flashed a handgun, state police said.

No children were on the bus, which is owned and operated by Durham School Services, state police said.

State police did not know which school district the driver was contracted with.

Both drivers were detained, but state police were waiting Thursday to review footage from the bus' surveillance camera before pressing charges. The names of the drivers were not released.

On Friday, the state police said they were still investigating the incident and that no charges have been filed. They asked anyone who witnessed the incident to contact the state police's Philadelphia Criminal Investigation Unit at 215-452-5216.

A spokeswoman for Durham School Services said in an email Friday that because the incident is under investigation, she would not be able to answer questions about the bus driver.
