POLICE are hunting three masked vandals who used hammers and a golf club to smash windows at Flagstone State Community College this week.
The trio broke 163 glass panels at the school, causing $40,000 worth of damage.
Police are examining CCTV footage from the incident which angered parents.
They believe the offenders are male, aged between 16 and 20, and thinly built.
Officers revealed they found blood at the scene.
The vandals had their faces covered. One was wearing black shorts and a dark top which had Straight outta Compton written on the back.
Another wore a red shirt and grey pants, while the third wore a dark outfit.
Police were called when a member of the public heard glass breaking at 9.10pm at the school on the corner of Poinciana Drive and Homestead Drive.
Sergeant Lawrie Catterson urged anyone with information to get in touch.
"Anyone who knows anything should contact Crimestoppers or Policelink," he said.
"They are senseless vandals."
The school conducted lessons in another classroom while repairs began.
Parents took to social media to slam the offenders.
"Thanks you idiots," Facebook user Tracey Anne wrote.
"Now our kids have to be in the stinking hot sports hall all day.
"Once found out, they should be made to pay for or work off the amount it costs to replace 200 windows."
Another woman said the vandals were disgusting humans.
A government spokeswoman refused to elaborate on security upgrades for the school after the incident.
"We would prefer not to give information on the school's security arrangements," she said.
The spokeswoman said reports that students were in the school hall all day were not true.
"Assembly was held in the morning instead of form or year level assemblies, and some classes were relocated to different classrooms for the day," she said.
"The student services team was available to provide support for students and the college community."
