London police and fire inspectors are investigating a case of arson at a northwest London elementary school Tuesday morning.
Firefighters were called to Wilfrid Jury Public School at 950 Lawson Road at around 5:06 a.m. after alarm bells sounded.
Upon arrival, smoke was visible inside the building and sprinklers were activated.
Fire officials say there was a broken window at the back of the building, along with signs of forced entry inside. There was fire set inside a classroom, which was extinguished by the sprinkler system.
An early estimate pegs the damage at around $20,000.
There are currently no suspects in custody, or suspect descriptions at this time.
The Thames Valley District School Board says all summer programs and childcare will be open, with some classroom adjustments.
