Nearly 150 people reported being pricked with needles during France’s annual Fête de la Musique over the weekend, reviving fears linked to unexplained syringe attacks.

French police recorded 13 cases in Paris alone and have arrested at least 12 individuals nationwide. Authorities have not confirmed whether any substances were injected, and investigations are ongoing.

The incidents echo a surge of needle-spiking reports from 2022, when French police logged more than 1,000 cases at clubs, bars and festivals.

Ahead of this year’s event, social media users shared safety warnings, particularly aimed at women, urging vigilance and immediate medical attention in the event of an attack.
