Two 15-year-old boys face arson and burglary charges over an alleged vandalism rampage including a deliberately-lit fire at Newcomb Secondary College early on Monday morning.
Fire crews rushed to the school about 1am to douse the blaze, which tore through two buildings causing extensive damage.
Firefighters took about an hour to bring the blaze under control.
Newcomb Secondary College was not using the building, the school posted on social media about 7am on Monday.
“It’s all over Facebook that there were firetrucks at the school overnight,” the post read.
“This is true but it was an issue in E-block, the building we don’t use, and it is all under control. School will proceed as normal today.”
The E-block is about 100m away from the school’s main building.
Geelong detectives arrested the two youths later that morning before charging them with criminal damage by fire and damaging multiple vehicles in Newcomb.
Police also charged the pair over an alleged burglary at Newcomb’s Not Quite Right store.
The teens were bailed to appear before a children’s court early next year, police said.
“We are appealing for any witnesses or anyone that has had their car damaged around this area last night,” a police post read on Monday.
“We believe there might be a few more victims that have not reported their vehicles damaged to police.”
Witnesses or anyone affected by the incidents can phone Crime Stoppers on 1800 333 000 or Geelong Police Station on 5225 3100.
