SWEET-TOOTHED juvenile delinquents have had a run-in with the law after breaking into a Toowoomba school, smashing windows and laptops and trying to bake a chocolate cake.

Toowoomba Police sergeant Greg Wheeler said officers nabbed a nine-year-old boy and a girl, 11, who broke into Clifford Park Special School about 3.45pm on Sunday.

The not-yet-seasoned vandals set off intruder alarms when they forced entry to the school's swimming pool complex.

They had smashed a glass-panel door to gain entry before busting a hole into the pool's cover and going for a dip.

Police arrived at 4.15pm and a short chase ensued.

They apprehended the young offenders and assessed the mess left in their wake.

"They had broken a number of laptop computers and an iPad," Sgt Wheeler said.

The home economics block was also vandalised, kitchen utensils thrown across the classroom and a hole punched through a door using a wooden hammer.

"They also tore open a chocolate cake mix and tried to blend it with an electric mixer," Sgt Wheeler said.

"As a result, it was spread throughout the room."

The children will be dealt with through the youth justice process.
