In what is being described as a classic case of cops and rubbers, Adelaide police have today taped off a local popular walking trail, after joggers reported the sighting of a partially buried eraser that had been stabbed over 40 times.

“I don’t know what kind of sick individual would do this,” shocked investigators told the press today. “Our criminal profilers are asking the public to be on the look out for a person or persons between the ages of six or twelve, who may exhibit signs of boredom or frustration at being forced to sit in class all day.”

“We are yet to determine the weapon, but we believe it may some form of makeshift shiv constructed of sharpened wood with a metal tip.”

It is the second rubber related crime to hit Adelaide in as many weeks, with authorities also having warned locals to be on the lookout for scammers claiming the dark end of erasers could remove pen.

“It’s worrying how prevalent this misinformation is,” explained a representative for fraud watch. “It’s up there with ‘pull here’ tabs that don’t work and ‘best before’ dates on food as some of the most heinous scams we’ve seen.”
