Peter Oakley discovered the syringe in an easter egg his mother had purchased from the Canterbury Garden Woolworths in Kilsyth.
“Keep your eyes out before giving choc rabbits to friends or kids. Hopefully the d*ckhead that did this did it only once as a joke,” he wrote in a Facebook post.
“Will be reporting this tomorrow.”
In a comment on his Facebook post, which has been shared over 4960 times, Oakley said it “looks like someone peeled back the foil and jammed it inside and then put the foil back in place”.
“The loose bit of chocolate was still inside,” he said.
However, Facebook users have taken to Woolworths’ official page claiming the story is fake.
“Woolies i sniff a fake trying to get money out of you so becarful.. This is like a new low,” Lisa Bingochicky posted.
It comes just a days after a Woolworths customer complained that they had found a dead cockroach in an easter egg box.
