Police in Europe report hundreds of unexplained "needle spiking" attack on club, concert-goers

Authorities in France are 300 cases in recent months of random needle spiking attacks at concert and clubs.

The authorities and doctors are investigating the cases but say the "why" and "what" remain a mystery.

No arrests have been made so far in connection with the incidents. 

The victims of needle spiking include men and women alike from cities stretching from Paris to Toulouse.

Needle spiking emerged last year and and spread across the European nightlife, according to the Associated Press. 

Typically, most of these attacks have been centered on young women. GHB, a date rape drug also known as Liquid Ecstasy, is common substance used in nightclubs. But no cases sexual of assault has been reported. Additionally, only one case of robbery was reported.

On May 4, 18-year-old Tomas Laux went to rap concert where he was needle spiked. His symptoms included feeling groggy, tired, and some dizziness. He also reported having an "unusual little skin puncture on his arm and a bruise" and went to the hospital, also according to the wire service. 

“I’ve given up going to concerts since it happened,” Laux said.

Like all the other victims of needle attacks, Laux was tested for HIV and hepatitis. He resulted in a negative result, but doctors still fear the possibility of disease for others.

The wire service quoted Dr. Emmanuel Puskarczyk, head of the poison control center in the French city of Nancy, saying, "We didn’t find any drugs or substances or objective proof which attest to ... administration of a substance with wrongful or criminal intent. What we fear the most is people contracting HIV, hepatitis or any infectious disease" from these attacks.

Only two other people tested positive for GHB, but authorities are hesitant to put the blame on the needle attack. The GHB within the needle would have to injected for multiple seconds which would likely alert the victim. An official with the national police agency states how it was more likely that the two people ingested it from a drink.

Last week, vocalist Alison Lewis, also known by her stage name Zoè Zanias, was spiked with a needle in Germany. Unlike, the groggy-headache like symptoms in the majority of the needle attacks, Lewis said she felt a numbness and temporary amnesia.

"I did not black out – instead experiencing the whole thing as an abstract psychedelic horror trip," Lewis said on her Instagram account.
