Preliminary tests fail to find any substance in systems of women targeted with needle in Newcastle pubs

Detectives are still searching for a motive on why six women were targeted by needle-sticks after preliminary toxicology results returned clear of illegal drugs or prescription medication.

The mystery surrounding multiple women discovering needle marks on their bodies after partying at Newcastle pubs has deepened after initial toxicology tests failed to find any trace of illegal or prescription drugs in their systems.

At least six women came forward to report finding the bizarre injection marks, many of their thighs, after frequenting at least five different establishments over one December weekend.

Some of the women reported feeling nauseous and light-headed while at least one Central Coast woman blacked out and needed hospital treatment.

The apparent needle mark on the thigh of one of six women who have gone to police to report being targeted.

But the motive behind why the women may have been targeted remains unclear after the toxicology tests failed to find any trace of any substance.

Police have warned the results were preliminary and more testing had to be performed.

And the time span between the women being jabbed and when blood tests were taken could have allowed any substance to leave their systems before it could be detected.

The troubling needle-spiking claims occurred over the December 3-4 weekend where at least six women independently told authorities they had been targeted.

At least one woman’s terrifying ordeal, where she quickly became ill and later lost consciousness before being hospitalised, includes hazied memories of an unknown man “hanging around” and trying to touch her as she battled to get her eyes to focus.

Detectives are still searching or answers as to why six women may have been stuck with a needle on one weekend in Newcastle.

The 20-year-old would later spend a night in hospital and discover a needle mark on her thigh.

The reports prompted a quick response from publicans, who put bar and security staff on notice and asked patrons to look after each other.

There have not been any other similar reports since the December weekend, suggesting any possible predator may have either been visiting Newcastle or had gone to ground following significant media and social media coverage.
