Some 145 revellers have been stabbed with syringes in a wave of horror attacks at a music festival in France.

Victims, who were largely teenage girls, were taken to hospital for toxicology tests after fears they could have been injected with a mystery poison.

Some reported feeling unwell following the pricks.

Millions took to the cobblestone pavements across France on Saturday to attend a street music festival called Fête de la Musique (World Music Day).

The stabbings happened across France with 13 jabbed in Paris after “unprecedented crowds” hit the capital, according to cops.

Disgusting calls on social media had spread before the festival calling for women to be stabbed, according to Le Monde.

French cops have arrested 12 people over the sick act.

They have not clarified if the syringes were spiked with a chemical – such as date-rape drug GHB.

Ten girls are alleged to have been attacked by one man with a syringe in the northeastern French city of Metz.

Cops tracked the suspect down by using CCTV footage, according to mayor Francois Grosdidie.

He said: “The municipal police identified him on Rue Serpenoise, arrested him, and made him available to the National Police and the Justice Department.

“I hope that the investigation, particularly through the examination of his cellphone, will lead to the identification of other attackers.”
