A fire which torched part of a Bay of Plenty school overnight is being treated as suspicious.
The fire damaged the exterior wall of Whakātane's Allandale School on King St.
Firefighters were called to the blaze at 6.40pm, a Fire and Emergency NZ spokeswoman said.
"It was a small pre-fab fire on an external wall," she said.
"A fire investigator has gone out to it."
