Two students and a driver escaped after a Drexel University bus caught fire in Center City Friday night.

The bus was at the corner of Market and South Juniper streets around 10:30 p.m. when the front of the vehicle burst into flames. The driver and two students who were on the bus at the time managed to get out unharmed.

“The fire went on for about 30 to 45 minutes before police and fire officials arrived on scene,” said 21-year-old Pete Zaleski, who witnessed and recorded the fire. "No one was injured but it left molten plastic and broken glass all over the street along with the smoke filling the entire block in the smell of burning plastic rubber."

Firefighters later arrived at the scene and put the fire under control.

Officials have not yet revealed the cause of the fire. They continue to investigate.
