Unknown perpetrators profanated a tabernacle. A chalice and consecrated hosts were stolen. Police was notified about the devastation, but the perpetrators remain unknown. The following Sunday morning Mass in the church had to be moved to the neighboring town of Dagneux. The Notre-Dame-des-Marais church had to be closed for five days.
