A DEAD koala with a $50 note stuffed in its mouth has people scratching their heads after it was dumped outside the Heywood police station.
Sergeant Jason Vontunk was working alone on Saturday when he heard a thud sound outside the Heywood police station about 10pm.
He told The Standard he looked out the window and saw a figure on the driveway.
"I shone the torch on it and saw it was a dead koala," he said.
"I looked around because I didn't know if I was being set up.
"I called another unit in from Portland and we then found $50 stuffed in the koala's mouth.
"There was no other message connected to it. It was absolutely bizarre.
"We had a sinister turn on it at first but we have no explanation as to why it occurred.
"At this stage there's no offence attached to it. We think the koala was hit by a car.
"At the end of the day $50 will go to consolidated revenue because who's going to admit losing $50 in a koala's mouth?
"It's a bit more sinister than a prank."
Victoria Police spokeswoman Melissa Seach said police were not investigating the incident, because it was not clear if the koala had been killed deliberately or run over by a car.
"It looks pretty bloody," she said.
