A dozen mini school buses were damaged when flames broke out in a parking lot in the Bronx. Police are investigating whether the fire was accidental or arson. The head of the bus yard told Eyewitness News exclusively that authorities are reviewing surveillance video. Cell phone video showed the flames at around 1:30 a.m. Friday. Firefighters put the fire out in about an hour. It happened at the Logan Bus Company's parking lot at 1624 Stillwell Avenue. It houses a total of 150 buses. The burned buses were late model, air conditioned buses that were insured. This comes just a couple weeks before the start of the new school year in New York City.
