A resident found a needle at Bortolo Oval, Greenfields.
Lorraine Price is warning residents to be careful after she found the needle at 1pm on April 5.
“You druggies need to get rid of these things before kids get hold of them,” she said.
“Shame on you.”
Ms Price picked up the needle and put it in the bin.
The oval is used by sporting groups and many residents use the oval for recreation, particularly in the school holidays.
