SASKATOON (CP) -- Fire officials in Saskatoon are hoping a fire bug isn't at work.
For the second time in less than two months, fire crews were called to put out flames in a portable school classroom early Sunday morning.
The $100,000 blaze broke out sometime before 4 a.m. at Greystone Heights, an elementary school in the city's east end, said Battalion Chief Jim Dubois.
``There was no smoke or fire damage to the school itself,'' he said.
``Arson investigators have told me it's an arson fire.''
Dubois said another portable classroom burned down at a school in Saskatoon's north end just a few weeks ago.
``This is the second fire we've had in one of these portable units in about a month-and-a-half. I hope this isn't a pattern that's going to be set,'' he said Sunday.
``We've had problems in the past with garage fires and car fires but that's subsided in the last month-and-a-half,'' Dubois said.
``We were getting calls almost on a nightly basis.''
Fire officials have posted personnel at the scene but Dubois said the burned out structure at Greystone Heights would likely be plowed flat Monday.
Dubois said by the time fire crews got to the scene shortly after 4 a.m. Sunday, fire was already belching out of the roof of the portable classroom.
There was no smoke or water damage to the rest of the school and no one was hurt during the incident he said.
