A CARELESS prank left Toni Leitch out of pocket more than $600 after what was believed to be a banksia pod was hurled at her car late last week.
Ms Leitch was driving home along Sunderland Dr with her partner Shane and nine-year-old son when they heard a loud bang.
"I thought I had run over a big stick or something," she said.
She stopped the car to investigate and discovered the broken pod along with about seven shopping bags filled with faecal matter.
Ms Leitch pulled the car over to call the police.
Shane said he had heard voices and a mobile phone go off in bushes nearby.
Police arrived with sniffer dogs in an attempt to find the culprits, however they were unsuccessful.
Ms Leitch said her teenage son told her that his mate had seen kids throwing bombs at cars at the scene.
While the pod did not do much damage to the car, Ms Leitch was upset that it was something she had to pay for.
"If police can't find any leads then I have to pay for it, it's not fair," she said.
"They must have thrown it hard. It hit the car that loud it was unreal."
Ms Leitch said she thought the culprits were bored kids on school holidays.
"I can't be the only one that it's happened to."
She called for the public to come forward with information.
"Please submit what you know; let's get them."
Officer in Charge of Bribie Island Police Station Senior Sergeant David Crawford-Raby confirmed police were looking for the offenders.
"If anyone has information contact police," he said.
Snr Sgt Crawford-Raby warned throwing water bombs and other objects at cars was dangerous.
"It's foolish and dangerous. Fortunately in this instance no one was hurt."
