The night will have been restless for the inhabitants of Drefféac (Loire-Atlantique). A hundred revelers met for a rave party on land on Île Biron, northeast of the town, in the marshes. The music started ringing out around 11 p.m. Saturday, March 19, until the next day, a little before 11 a.m.
The area was secured by police. The mayor of the town has visited the site several times. Two of the participants were taken by ambulance to hospital.
