Baltimore County fire officials are investigating an arson that destroyed a Parkville High School portable classroom early yesterday.

"We have a reason to believe that someone set a fire to the classroom," said Mark Hubbard, spokesman for the Baltimore County Fire Department.

Firefighters quickly contained the one-alarm fire that broke out in the trailer in the 2600 block of Putty Hill Ave. about 5 a.m.

No one was inside, and the fire did not spread to the main building.

The classroom, which accommodated 25 high school students, had $9,000 in damage, Hubbard said.
